Ddr 3 667: Why is my DDR3 RAM running at 667MHz?

RAM Memory Speeds & Compatibility

Adding more memory to your PC is one of the best and easiest ways to improve system performance. But before clicking that “buy” button on this or any website, it’s important to make sure the memory you are buying is compatible with your PC.

DDR4 memory is the latest generation of memory for computing applications and offers many benefits over previous generations of memory including lower latencies, higher speeds, and more. One thing to keep in mind is that memory needs to be the same type — memory modules are not forward or backward compatible in terms of generation types so DDR3 will not work in DDR2 or DDR4.

Memory is designed to be backward compatible within its generation, so generally speaking, you can safely add faster memory to a computer that was designed to run slower memory. However, your system will operate at the speed of the slowest memory module installed.

We recommend that you use either the Crucial Memory Advisor™ or Crucial System Scanner to find the right memory for your computer. Rather than give memory modules catchy names, the industry refers to modules by their specifications. But if you don’t know a lot about memory, the numbers can be confusing. Here’s a short summary of the most popular types of memory and what the numbers refer to.

 

Generations of memory explained

For double-data-rate memory, the higher the number, the faster the memory and higher bandwidth. Occasionally DDR memory is referred to by a «friendly name» like «DDR3-1066» or «DDR4-4000.» When written this way, the number after «DDR» represents the generation. The number after the generation refers to the component’s data transfer rate per second (/s). When referenced by the industry name, the numbers that follow «PC» and the generation refer to the total bandwidth of the module.

 

DDR4 speeds

 

Friendly name Industry name Peak Transfer Rate Data transfers/second (in millions)
DDR4-2400 PC4-19200 19200 MB/s 2400
DDR4-2666 PC4-21300 21300 MB/s 2666
DDR4-2933 PC4-23400 23400 MB/s 2933
DDR4-3000 PC4-24000 24000 MB/s 3000
DDR4-3200 PC4-25600 25600 MB/s 3200
DDR4-3600 PC4-28800 28800 MB/s 3600
DDR4-4000 PC4-32000 32000 MB/s 4000
DDR4-4400 PC4-35200 35200 MB/s 4400

 

DDR4 speeds start at 2400 MT/s and offer faster speeds and responsiveness than all other generations of memory. Optimized for gamers, professional designers, and enthusiasts who need to maximize data rates, DDR4 is for those who want the most from their system. Gaming modules typically have faster speeds, lower latencies, and unique design and heat spreaders. 

 

DDR3 speeds

PC66 memory is SDRAM designed for use in systems with a 66MHz front-side bus. It is used in the Pentium 133MHz systems and Power Macintosh G3 systems. FPM and EDO speeds are written in nanoseconds (ns), which indicates their access time; the lower the number, the faster the memory (it takes fewer nanoseconds to process data).

 

About adding faster memory …

It may seem confusing, but faster memory will not necessarily make your system faster. You can’t speed up your computer by adding faster memory if any of the other components in your computer (your processor or other memory modules) operate at a slower speed.

 

Keep in mind, that the right memory for your computer is the kind of memory it was designed to take. Check your system manual or look up your system in the Crucial Advisor tool™ or System Scanner to find the memory guaranteed to be 100 percent compatible or your money back!

Levels of cytokines in postmenopausal women depending on individual polymorphisms of the VDR, COL1A1, LRP5 genes | Maylyan

Introduction

Osteoporosis (OP) is a chronic systemic progressive metabolic disease of the skeleton, which is characterized by a decrease in bone mineral density and a violation of its microarchitectonics, resulting in an increased risk of fractures. The most relevant in terms of prevalence, social and economic significance is postmenopausal OP.

Currently, the main objective approach in the diagnosis of OP is the determination of bone mineral density by densitometry, which significantly depends on external and genetic factors [1]. Moreover, the contribution of the genetic component to the etiopathogenesis of the disease reaches 60-80% [2][3][4]. The performed studies have shown that mineral density indices of various parts of the skeleton in postmenopausal women are associated with certain polymorphisms of the genes of the vitamin D receptor (VDR), type 1 collagen 1-alpha chain (COL1A1), protein associated with the type 5 low-density lipoprotein receptor ( LRP5). It was found that postmenopausal OP in the region of the lumbar vertebrae L1-L4 is associated with the GG genotype of the rs1544410 polymorphism of the VDR gene [5]. Osteoporotic changes in the zone of the proximal parts of the right and left femurs, as well as the necks of the right and left femurs, develop less frequently in women with the CC genotype and more often in carriers of the CA genotype and the A allele of the rs11079 polymorphism46 of the COL1A1 gene [6]. An increased risk of developing postmenopausal OP is characteristic of women with the GT genotype and the T allele of the rs1800012 polymorphism of the COL1A1 gene, while the GG genotype of this polymorphism is combined with a low probability of developing the disease [7]. In addition, among women with OP of the lumbar vertebrae L1-L4 and the left femur, the frequency of registration of the CT genotype and the T allele of the rs3736228 polymorphism, the GA genotype and the A allele of the rs4988321 polymorphism of the LRP5 gene is increased, and among healthy women, the CC and GG genotypes of the above are more often recorded. polymorphisms [8].

Recent advances in the study of the pathogenesis of postmenopausal OP indicate a key role in the development of the disease of immune factors. Changes in the balance of cytokines in postmenopausal women caused by estrogen deficiency cause inhibition of osteoblastogenesis, an increase in the activity and number of osteoclasts, which contributes to increased bone resorption [9][10]. Given the genetic component in the etiopathogenesis of OP and the important role of cytokines in the regulation of bone metabolism, however, to date there are no studies aimed at studying the features of the cytokine status in postmenopausal women with various polymorphic variants of the VDR, COL1A1 and LRP5 genes.

Purpose of the study: to study the serum levels of pro-inflammatory and anti-inflammatory cytokines in postmenopausal osteoporosis, as well as their changes depending on the polymorphisms rs1544410 of the VDR gene, rs1107946 and rs1800012 of the COL1A1 gene, rs3736228 and rs4988321 of the LRP5 gene.

Materials and methods

The work was carried out at the Donetsk National Medical University. 180 postmenopausal women (60.0±0.77 years) were examined. The study did not select women who took hormone replacement and anti-osteoporotic therapy, glucocorticosteroid drugs. Patients with ovariectomy, endocrine and metabolic disorders, hematological diseases, neoplastic conditions, chronic kidney and liver diseases, autoimmune pathology, systemic connective tissue diseases, and chronic inflammatory diseases were also excluded.

Women underwent osteodensitometry of the lumbar vertebrae L1-L4, proximal sections and necks of the left and right femurs using dual-energy X-ray absorptiometry. Densitometers Discovery W QDR Series X-Ray Bone Densitometer (HOLOGIC Inc., USA) and Prodigy (GE Medical Systems LUNAR, USA) were used. The results were expressed as bone mineral density and T-score.

The levels of interleukins (IL) -1β, -4, -6, -8, -10, -17A, tumor necrosis factor alpha (TNF-α), interferon gamma (INF-γ), osteoprotegerin (OPG), nuclear factor receptor activator ligand kB (RANKL). The studies were carried out using enzyme immunoassay test systems manufactured by Vector-Best (Koltsovo village, Novosibirsk region, RF), eBiosciences (San Diego, CA, USA), Biomedica Medizinprodukte (GmbH & Co KG, A- 1210 Vienna, Germany).

Testing of polymorphisms 283 A>G (BsmI, rs1544410) of the VDR gene, -1997 C>A (rs1107946) and 1546 (6252) G>T (Sp1 S>s, rs1800012) of the COL1A1 gene, 3989 C>T (Ala- 1330Val, rs3736228) and 1999 G>A (Val667Met, rs4988321) of the LRP5 gene were carried out by polymerase chain reaction using the appropriate kits and a DT-96 amplifier manufactured by DNA-Technology (Moscow, RF).

Statistical processing of the obtained results was performed using the programs «MedStat» and «STATISTICA for Windows 6.0» (StatSoft, Inc.). To test the distribution of indicators for normality, we used the chi-square test (χ 2 ). Due to the fact that the distribution of most of the studied indicators differed from the normal one, nonparametric methods were used in descriptive statistics. Median (Me) and median error (m) were calculated. For pairwise comparisons of centers of independent samples, the Wilcoxon W-test was used. Differences were considered statistically significant at P<0.05.

Results

At the first stage of the statistical analysis of the obtained data, the levels of cytokines in the blood serum of women were assessed depending on the state of their skeletal system. To do this, based on the results of osteodensitometry, all examined were divided into 3 groups — healthy (n=37, T-criterion values ​​up to -1.0 standard deviations from peak bone mass), with osteopenia (n=84, T-criterion values below -1. 0 to -2.5 standard deviations) and OD (n=59, T-test is -2.5 standard deviations and below). At the same time, the control group, groups of women with osteopenia and OP did not differ significantly in age (59.0+1.71, 60.5+1.09 and 60.0+1.44 years, respectively, P>0.05) and the duration of the postmenopausal period (respectively 10.0+1.73, 10.0+1.09 and 12.0+1.22 years, P>0.05).

It was found that patients with OP, compared with the control group, were characterized (Table 1) by higher serum levels of IL-1-β (P<0.001), IL-8 (P=0.048), IL-17A (P=0.002), TNF-α (P=0.031), RANKL (P=0.032) and reduced levels of IL-4 (P=0.027), IL-10 (P<0.001). Similar differences were also found between groups of women with OP and osteopenia in terms of levels of IL-1-β (P=0.017), IL-8 (P=0.031), IL-10 (P=0.018), IL-17A (P <0.001), TNF-α (P=0.002), RANKL (P=0.023). It should be noted that patients with osteopenia also differed from the control group in the values ​​of IL-1-β (increase, P=0.004) and IL-10 (decrease, P=0. 008).

In addition, there were no specific features of the three groups of women in terms of serum INF-γ and OPG (P>0.05). In addition, no differences were found between the selected groups and in the OPG / RANKL index, the values ​​of which in healthy women and patients with OP and osteopenia were 28.0+21.1, 25.1+6.65 and 23.1+, respectively. 16.6 (P>0.05).

To study the associations of the rs1107946 polymorphism of the COL1A1 gene with cytokine levels, the examined women were divided into 2 groups. Separately, women with the CC genotype (n=126) were identified, which, in previous studies, was associated with a low risk of developing OP [6]. The second group (n=54) consisted of patients with the CA genotype (n=46) and a small number of individuals with the AA genotype (n=8). Similarly, two groups of women were distinguished according to the rs1800012 polymorphism of the COL1A1 gene, based on the fact that an increased risk of developing postmenopausal OP is associated with the GT genotype and the T allele, while the GG genotype, on the contrary, is associated with a low probability of the disease [7].

Comparative analysis of women with different variants of the rs1107946 polymorphism of the COL1A1 gene (Table 3) showed that individuals with CA or AA genotypes, compared with carriers of the CC genotype, had higher levels of IL-4 (P = 0.006), IL- 6 (P=0.023), IL-8 (P=0.023), IL-10 (P=0.012), RANKL (P=0.022). Women with GT or TT genotypes of the rs1800012 polymorphism of the COL1A1 gene were distinguished from those with the GG genotype by reduced values ​​of IL-10 (P=0.007), OPG (P=0.013), OPG/RANKL index (P=0.042).

It should be noted that none of the above polymorphisms of the COL1A1 gene showed associations (P>0.05) with IL-1, Zh-17A, TNF-α, INF-γ. No differences were found among women depending on the polymorphisms of the LRP5 gene (Table 4) both in the concentrations of the above cytokines and a number of others (IL-4, IL-6, IL-8, OPG, RANKL). At the same time, individuals with the GA genotype of the rs4988321 polymorphism had lower IL-10 values ​​than those with the GG genotype (P=0.003). A similar decrease in the content of IL-10 in the blood serum was determined (P=0.007) in women with CT or TT genotypes of the rs3736228 polymorphism.

Discussion

Thus, the performed studies demonstrate significant changes in the status of cytokines in postmenopausal OP, which are characterized by an increase in serum concentrations of pro-inflammatory cytokines IL-1-β, IL-8, Zh-17A, TNF-α, RANKL and a decrease in the levels of anti-inflammatory cytokines IL-4, IL-10. The results obtained are consistent with modern ideas about the role of the immune system in the development of postmenopausal OP [9][10][11]. It has now been proven that a decrease in postmenopausal estrogen levels is accompanied by increased proliferation and activation of T cells, as well as inhibition of their apoptosis. As a result, the number of activated T-lymphocytes increases and their production of pro-inflammatory cytokines increases. The result of these changes is chronic stimulation of osteoclasts, leading to increased bone resorption and the development of OP. In this regard, it is believed that immune disorders play a key role in the pathogenesis of bone loss, and OP is called a chronic immune-mediated disease [9].][ten].

Analysis of cytokine levels depending on genetic markers showed that those genotypes of VDR, COL1A1 and LRP5 gene polymorphisms, which in previous studies showed an association with an increased risk of OP [5][6][7][8], for the most part found associations with increased concentrations of pro-inflammatory cytokines and decreased anti-inflammatory cytokines. And this is natural, since the above genotypes (the GG genotype of the BsmI polymorphism of the VDR gene, etc.) are more often registered among patients with OP.

At the same time, it is necessary to note the peculiarities of the cytokine status of women with some polymorphic variants of the studied genes. For example, the rs3736228 and rs4988321 polymorphisms of the LRP5 gene were associated with changes in the levels of only one cytokine (IL-10), while the rs1800012 polymorphism of the COL1A1 gene was associated with only two cytokines (IL-10 and OPG). It is important to note that significant associations of OPG serum concentrations were characteristic only with the genotypes of the rs1800012 polymorphism of the COL1A1 gene. At the same time, there were no changes in OPG levels depending on other studied polymorphisms, as well as on the state of the skeletal system of women.

To date, possible mechanisms that could explain the association of genotypes of COL1A1 and LRP5 gene polymorphisms with changes in immune parameters remain unknown. It is possible that the role of these polymorphisms in the development of OP is not even due to their direct effect on the production of cytokines. And the revealed links with the levels of cytokines are mediated by other reasons, due to complex interactions in the «gene-gene», «gene-external factors» systems. After all, OP is a polygenic disease. Its etiopathogenesis involves many genes that mutually influence each other, the phenotypic manifestations of which are realized under the influence of a wide range of external factors (the presence and severity of estrogen, vitamin D and calcium deficiency, physical inactivity, smoking, racial differences, etc. ). This is confirmed by the opinion that mutations in the COL1A1 gene involved in the formation of collagen cause structural and functional changes in the main component of the connective tissue and thus contribute to the development of OP. In particular, one of these mutations is the rs1800012 polymorphism in the COL1A1 gene, which leads to an increase in the ratio of α-1 and α-2 collagen chains and, ultimately, to a deterioration in bone microarchitecture and an increase in the risk of fractures [12][13].

Mutations in the LRP5 gene are known to have a direct effect on bone cell function, bone formation and bone tissue resorption. The protein associated with the type 5 low density lipoprotein receptor, which is encoded by the LRP5 gene, is an important factor in signaling via the canonical Wnt signaling pathway [14]. The canonical (β-catenin-dependent) Wnt signaling pathway is one of the most important molecular signaling pathways that regulates embryonic development and differentiation of cells, including cells of the skeletal system. Disturbances in Wnt signaling, which may be caused by mutations in the LRP5 gene, are accompanied by an increase in the intensity of bone formation in the direction of increase, and in the direction of decrease, by a decrease in bone mass and skeletal disorders [15]. At the same time, it is necessary to point out the important role of the canonical Wnt signaling pathway in the regulation of not only bone cells, but also cells of the immune system [16]. Based on this, it can be assumed that the effect of LRP5 gene polymorphisms on the risk of developing AP may be indirect and through the impact on the function of dendritic cells and lymphocytes. Among other things, it has been shown that a decrease in LRP5/6-mediated signaling in dendritic cells leads to an increase in the differentiation of effector T cells, an increase in the production of pro-inflammatory cytokines, and a decrease in the production of IL-10 [17][18][19]. This is consistent with our results demonstrating an association between the GA genotype of the 1999 G>A polymorphism (Val667Met, rs4988321) and the CT or TT genotypes of the 3989 C>T polymorphism (Ala1330Val, rs3736228) of the LRP5 gene with a decrease in serum levels of IL-10.

The mechanisms by which VDR gene mutations, including the BsmI polymorphism, are involved in the development of osteoporotic changes are still debatable. It is assumed that risk alleles cause a decrease in the expression of this receptor [15], which is accompanied by a decrease in the regulatory effects of vitamin D on the cell. There is a picture of vitamin D deficiency even with its sufficient amount. The result of this is the inhibition of the genomic effects of the vitamin on calcium absorption in the intestinal epithelium. Deficiency of the direct mechanisms of vitamin action on the cells of the skeletal system, including osteoblasts, also develops [20]. All of these may be important links in the pathogenesis of OP. In addition, the regulating effect of vitamin D on immune cells also suffers. To date, its important function in providing an immune response, including the suppression of excessive production of pro-inflammatory cytokines and an increase in the formation of IL-10, has been established [21]. Apparently, the presence of the GG genotype of the 283 A>G polymorphism (BsmI, rs1544410) is combined with a decrease in the effects of vitamin D on cells of the immune system, which may be accompanied by the changes in the cytokine balance that were identified in our work, namely, an increase in the levels of IL- 1-β, RANKL, OPG/RANKL index and a decrease in IL-10.

Conclusion

Thus, it was found that women with postmenopausal osteoporosis are characterized by a significant (P<0.05) increase in serum concentrations of IL-1-β, IL-8, IL-17A, TNF-α, RANKL and a decrease levels IL-4, IL-10. Polymorphic variants of the VDR, COL1A1 and LRP5 genes, which were associated with the development of postmenopausal osteoporosis, in most cases had a similar association with changes in the levels of the above cytokines. At the same time, features of the cytokine status in women depending on genetic polymorphisms were also found. The data obtained reflect important pathogenetic aspects of postmenopausal osteoporosis, including those depending on genetic factors, and can be used to develop individualized schemes for treatment and prevention.

First Moscow State Medical University. I.M. Sechenov” of the Ministry of Health of Russia (Sechenov University), Russia, Moscow

Purpose of the study. The study of the ratio of reproductive function (FR) and recurrent depressive disorder (RDD) in women.
Material and methods. 120 women with RDD and 120 mentally healthy women, 18–65 years old, were examined.
Results. Quantitative characteristics of RF in women with RDR and healthy women are presented. With depression, there is a later onset and irregularity of menstruation, earlier recovery of menstrual function after childbirth, the occurrence of PMS and premenopause, which leads to a decrease in the number of pregnancies, childbirth, and children. Depression negatively affects social and family adaptation. The most malignant in terms of the effect on FR are depressions that debuted in puberty, the least — with a debut in postmenopause.
Conclusion. Depressive disorders are associated with periods of hormonal adjustment. Depressive symptoms in PMS predict future depression or indicate incomplete remission. In women with RDR, menstrual and reproductive function is disturbed.

Social teacher — Fix Ekaterina Olegovna

tel. 316-69-92

Pedagogical experience — 5 years. 10 months Education — higher pedagogical.

A social educator is a person in a school whose activity is designed to unite the efforts of the family, school, community to provide comprehensive assistance and support in the development and upbringing of children.

The activity of a social pedagogue involves interaction with children, in the process of socialization of which various kinds of problems arise. The success of a child in school, the upbringing of a socially active person who can make independent decisions is the key to a person’s success in life. Every child is talented, every child is a whole world, it is only necessary to notice in time and help him discover his talent, based on his individuality and personal qualities.

The purpose of the work of a social pedagogue is to create conditions for the successful socialization of a child.

Areas of activity of a social pedagogue: diagnostic; consultative and educational; preventive; organizational and methodological.

In his socio-pedagogical activities, the social teacher is guided by the following legal documents:

  • the UN Convention on the Rights of the Child;
  • Constitution of the Russian Federation;
  • Civil, Family, Criminal Code;
  • Code of Administrative Offenses;
  • RF Law “On Education in the Russian Federation”;
  • Federal Law “On the fundamentals of the system of prevention, neglect and juvenile delinquency” dated June 24, 1999 No. 120-FZ

Activities 2021/2022 of the academic year

18. 11.2021 For students of the 7th, 8th grades of the State Budgetary Institution to the CPPS of the Admiralty District, preventive measures were held: in the 7-B class of class-class an hour on the topic «Legal Education», in which students got acquainted with the basic rights and obligations of a person and a citizen, connected parts of proverbs on legal topics, determined what is a right and what is an obligation. In the 8th grade — a classroom hour dedicated to the prevention of extremist and terrorist tendencies among the youth, during which the students brought out the definition of tolerance for themselves and each participant presented his own project of the emblem of a tolerant society.

19.11.2021 specialists of the school escort service (social teacher, teacher-psychologist) conducted a lesson of kindness in the 1st grade. The purpose of the lesson is to cultivate a respectful attitude towards people, a caring attitude towards animals and the environment. As part of the kindness lesson, the students determined for themselves what qualities are included in the concept of kindness, watched a cartoon on a given topic, and made a portrait of a kind person. At the end of the lesson, a communicative game «Compliments» was held, aimed at establishing a favorable atmosphere in the classroom and rallying the children’s team.

December 10 is celebrated as Human Rights Day around the world. It was on this day in 1948 that the United Nations Assembly adopted the Universal Declaration of Human Rights. Today, the school has carried out activities aimed at shaping the legal culture of young citizens of our country: For students 5-a, 5-b, 7-c, 11-a, the juvenile inspector of the ODN of the Ministry of Internal Affairs of Russia for the Admiralteysky district Javadyan R. R. gave lectures on legal topics. The event was very active and informative, the students asked their questions and offered their options for solving legal problems.

On January 26, 2022, specialists conducted class hours «Personality Builder» in grades 8, as well as a preventive lesson «Consciousness» for grade 7.
