    Pregnancy calculator guide or how to use pregnancy calculator? There are some questions which you are curious to find the answer about these. We covered briefly this topic for you. You will get the answer here also, What are pregnancy symptoms and due date calculation procedures?
  •  
    After getting married, every couple certainly wants to have a baby. So, when a wife gets pregnant, both she and the husband want to know as soon as possible when she will give birth. Usually, a married couple will go to a hospital and follow USG test to know the predicted birth date. However, you can actually calculate it by your own. You should know when your last period was started so then you are able to find a due date. Today, there is what is called pregnancy calculator. It can be used by everyone. If you are curious about it, let's pay attention to the following discussion.

Association between endogenous sex steroid hormones and inflammatory biomarkers in US men - 0 views

  • modest statistically significant inverse associations for total and calculated free testosterone, and modest positive associations for total and calculated free estradiol with CRP concentration
  • Estradiol concentrations were also weakly positively associated with WBC count
  • SHBG was weakly inversely associated with WBC
  • ...21 more annotations...
  • An association between testosterone and WBC count was not observed
  • These findings are consistent with the hypothesis that in men higher androgen concentration is anti-inflammatory, and higher estrogen concentration is pro-inflammatory.
  • the probability of elevated CRP concentrations (≥ 3 mg/L) decreased with higher total and calculated free testosterone concentrations, while the probability increased with higher total and calculated free estradiol concentrations
  • there is ample evidence supporting the immunosuppressive effect of androgens
  • The incidence of autoimmune diseases is higher in androgen-deficient men
  • Studies have shown that the induction of hypogonadism in older men is followed by a significant increase in IL-6 concentrations (Khosla et al. 2002), a potent stimulator of inflammation, and that activation of the androgen receptor exerts a direct anti-inflammatory effect
  • It has been suggested that the mechanisms for the immunosuppressive effect of androgens could be either a direct effect on the expression of inflammatory genes (Bellido et al. 1995; Asirvatham et al. 2006), or an indirect effect through inhibition of nuclear factor-kB activation
  • Estradiol is the major biologically active estrogen, and about 80% is formed in adult men from the aromatization of testosterone primarily in the adipose tissue
  • estrogen can stimulate the transcription factor C/EBP-β, which is involved in CRP transcription
  • Most prior cross-sectional studies have observed inverse associations between androgen concentrations and inflammatory biomarkers
  • A recent study in Chinese men showed that lower concentrations of total and calculated free testosterone were associated with higher CRP concentration
  • Data from the Boston Area Community Health Survey also reported inverse associations between testosterone and CRP concentrations
  • Total testosterone was inversely associated with WBC count (Tang et al. 2007; Schneider et al. 2009; Brand et al. 2012), but calculated free testosterone was not associated with WBC
  • The first trial found a decrease in CRP, interleukin-1β (IL-1β), and tumor necrosis factor-α (TNFα) but no changes in IL-6 and IL-10 concentrations between the active treatment and placebo arms
  • the majority of studies in the literature have not observed statistically significant associations between estradiol and inflammatory biomarkers in men, although several of them observed point estimates in the positive direction
  • total testosterone and estradiol compete for binding to SHBG, and seem to have opposite effects on the concentration of inflammatory biomarkers
  • A small randomized controlled trial of estrogen replacement therapy in prostate cancer patients showed an increase in CRP in the active treatment group versus the comparator group
  • Obese men are known to have lower androgen concentrations compared to their normal-weight counterparts
  • The strongest suggestion of an interaction was the inverse association between androstanediol glucuronide and CRP concentrations in obese participants, while the association was positive in the non-obese
  • A recent Chinese cross-sectional study observed stronger inverse associations between total testosterone and CRP concentrations in individuals with a BMI of 27.5 kg/m2 or greater
  • our results suggest that total and calculated free testosterone are modestly inversely associated with CRP concentrations, and that total and calculated free estradiol are modestly positively associated with CRP and WBC
  •  
    Study results suggest that higher Testosterone and lower Estrogen levels provide anti-inflammatory effects in men.  The inflammatory biomarker assessed here was CRP.  Low total and calculated free Testosterone was associated with an increase in CRP.  In contrast, total and free Estrogen was associated with an increase in CRP.  Estradiol increased WBC count and SHBG was inversely related to WBC count in this study.

Testosterone and Abnormal Glucose Metabolism in an Inner-City Cohort - 0 views

  •  
    This study of inner city men found low T associated with methadone use.  Narcotics are a known risk factor for low T.  The free T was calculated from serum.  This equilibrium dialysis is based on too many variables.  Look at the studies on equilibrium dialysis.  This study also found calculated free T was not associated with insulin resistance.  However, insulin resistance is a peripheral tissue dysfunction not a serum dysfunction.  So, a calculated free T (not reality) in the serum shows me nothing of the peripheral activity.  For example, inflammation has been shown to increase aromatase activity in the prostate tissue only.  The thinking in the conclusions of so many of these studies is soooo flawed.

    Computer Science Tuesday, April 25, 2023 Computer hardware Computer hardware is the physical components that make up a computer system. It includes everything from the central processing unit (CPU) to the monitor, keyboard, and mouse. Understanding the different types of hardware and how they work together is essential for anyone who works with computers. In this article, we will explore the various components of computer hardware, including internal and external components, and the peripherals that connect to them. We will also discuss the importance of hardware maintenance, the latest advancements in computer technology, and factors to consider when choosing the right hardware for your needs. Whether you are a computer technician, a gamer, or simply someone who uses a computer for everyday tasks, this article will help you better understand the world of computer hardware. Introduction to Computer Hardware Computer hardware refers to the physical components that make up a computer system. It includes everything from the processor and memory to input/output devices such as the keyboard and monitor. In this article, we will explore the different types of computer hardware and their functions. What is Computer Hardware Computer hardware refers to the physical components of a computer system. It includes all the components that can be touched, seen, and used to interact with a computer, such as the monitor, keyboard, and mouse. Hardware is different from computer software, which refers to the programs and applications that run on a computer system. History of Computer Hardware The history of computer hardware dates back to the 1820s when Charles Babbage, an English mathematician, and inventor, designed the first analytical engine, which was considered to be the first mechanical computer. With time, more complex electronic computers were developed, including the first Intel microprocessor in 1971. Since then, computer hardware has continued to evolve, becoming

Free Testosterone Measurement by the Analog Displacement Direct Assay: Old Concerns and... - 0 views

  •  
    the standard technique of "free testosterone" calculation today is via equilibrium dialysis.  This article describes the problem with current evaluation techniques of current free testosterone evaluation: "this method, although sensitive and reproducible, is cumbersome and not easily adaptable to automated methods".  Most values of "free testosterone" today are either calculated or estimated as this article points out.  Why not just measure with saliva?!

  •  
    Study finds variations in calculated free testosterone.  Most of the variability is from the total testosterone, lesser due to the formulas, and third to the SHBG assay.  The point here, is there are too many variables to place a lot of weight on calculated free T in serum. Jus test it in the saliva.

Genetic Determinants of Serum Testosterone Concentrations in Men - 0 views

  • mean serum testosterone concentrations were found to be lower in men with GG than in those with TT genotype for rs12150660
  • men with the CT genotype for rs6258 had lower serum testosterone concentrations than those with CC genotype.
  • The two autosomal SNPs identified by GWAS had a significant influence on the risk of having low serum testosterone (serum testosterone <300 ng/dl) in both the discovery and the replication cohorts with a combined odds ratio (OR) per minor allele of 0.72 (95% CI, 0.65 – 0.79) and 2.7 (95% CI, 2.1 – 3.5) for rs12150660 and rs6258, respectively
  • ...3 more annotations...
  • The risk of having low serum testosterone concentrations increased by the number of risk alleles with an OR of 1.62 (95% CI, 1.41 – 1.86) for each risk allele (Figure S4). Low serum testosterone concentrations were 6.5-times more prevalent in men with ≥3 risk alleles (30.1% prevalence of low serum testosterone) compared to men without any risk allele (4.6% prevalence of low serum testosterone;
  • SNP rs5934505 was associated with serum testosterone without SHBG-adjustment (combined p-value of 1.7×10−9) and with free testosterone (combined p-value of 6.7×10−15), but not with SHBG
  • The mean serum testosterone and calculated free testosterone but not SHBG concentrations were lower in men with T genotype than in those with C genotype for rs5934505
