This novel concept for realizing synaptic functions in organic resistive switching devices may provide a physical platform to advance the fundamental understanding of learning and memory mechanisms and develop a variety of neural circuits and neuromorphic systems that can be linked to artificial intelligence and next-generation computing paradigm.

To evaluate the presence and analyze the pathological changes within the testes of patients who died or recovered from severe acute respiratory syndrome coronavirus 2 (COVID-19) complications.

Testis tissue was collected from autopsies of COVID-19 positive (n=6) and negative men (n=3). Formalin-fixed paraffin-embedded tissues were stained with hematoxylin and eosin (H&E) and subjected to immunofluorescence for angiotensin-converting enzyme 2 (ACE-2) expression. Fluorescent-labeled tissue slides were imaged on a quantitative pathology scope with various zoom levels allowing for qualitative and quantitative interpretation. Tissue from four COVID-19 positive autopsy cases and a live seroconverted patient was imaged with transmission electron microscopy (TEM).

H&E histomorphology showed three of the six COVID-19 biopsies had normal spermatogenesis while the remaining three had impaired spermatogenesis. TEM showed the COVID-19 virus in testis tissue of one COVID-19 positive autopsy case and the live targets of COVID-19 infection. check details We found an inverse association between ACE-2 receptor levels and spermatogenesis, suggesting a possible mechanism of how COVID-19 can cause infertility.Severe Acute Respiratory Syndrome Coronavirus 2, which is quickly spreading around the world and causes coronavirus disease 2019, may attack the urogenital system. We thought that a summary of the current literature about urogenital disease associated with the virus would be useful for physicians treating patients with coronavirus disease 2019. PubMed was comprehensively screened for studies published from 2019 to 2020. Studies of coronavirus disease 2019 patients with kidney disease, reproductive system diseases, or urological cancer were included. Through reviewing current literature, we summarized that acute kidney injury is a risk factor for patients with coronavirus disease 2019 and is related to their survival. A diagnosis of chronic kidney disease increases the risk of infection. The therapy for kidney transplant patients should be cautious and implemented on a case-by-case basis. When the public health burden is too heavy to bear, a rational selection of treatment for patients with urological cancer is vital. The male reproductive system is at high risk of being attacked by the virus, which may cause damage to reproductive function, and the long-term effects require further study. So, the complications associated with the urogenital system should not be ignored during the course of infection treatment and more robust evidence of long-term effects on the urogenital system will be proposed as more studies are published.

Sexuality is very important for men's health. Currently, phosphodiesterase type 5 inhibitors (PDE5i) remain the first-line therapy for erectile dysfunction, and no other oral drugs or drinks are approved and used clinically to treat male libido or orgasm dysfunction. In reference to a pharmaceutical dosage document, growing health consciousness is said to have boosted yearly sales of supplement drinks to more than 170 billion yen (1.58 billion US dollars) in Japan. We have created a supplement drink comprised of testofen, L-citrulline, resveratrol, and caffeine. We hypothesized that our supplement drink would be effective for men with sexual dysfunction, and especially libido dysfunction.

In this study, men with sexual dysfunction received a placebo drink for 14 days or our supplement drink (testofen, 600 mg/d; L-citrulline, 800 mg/d; resveratrol, 300 mg/d; and caffeine, 40 mg/d) for another 14 days separated by a 7-day washout period. Patients continued on-demand use of PDE5i. The International Index of Erectile Function (IIEF) score and adverse events were assessed.

Twenty patients aged 30-47 years old were enrolled in and concluded the study with no adverse events experienced. The IIEF domains of desire frequency, erection frequency, erection firmness, erection confidence, intercourse satisfaction, ejaculation frequency, orgasm frequency, and overall satisfaction were significantly improved with our supplement drink.

This is the first study to show that our supplement drink may not only be effective for erection but also for libido, orgasm, and ejaculation.

This is the first study to show that our supplement drink may not only be effective for erection but also for libido, orgasm, and ejaculation.Obesity is one of major health burdens of modern society as it contributes to the growing prevalence of its related comorbidities, such as diabetes, cardiovascular diseases, and some cancers. A series of innate immune cells, especially macrophages, and adipocytes have been implicated in the pathogenesis of obesity. Mitochondrial dysfunction, which is induced by obesity, are critical mediators in initiating inflammation in macrophages and adipocytes, and subsequent systemic insulin resistance. In this review, we discuss new findings on how obesity impairs mitochondrial function in macrophages and adipocytes and how this dysfunction contributes to obesity and its comorbidities. We also summarize drugs that treat metabolic diseases by targeting mitochondrial dysfunction.

The aim of this study was to evaluate the combined effect of

2039 A/G and

-29 G/A single nucleotide polymorphisms (SNPs) on the male reproductive function in a cohort of Sicilian men.

One-hundred thirty Sicilian men were enrolled and underwent blood withdrawal for hormone measurement and

2039 A/G and

-29 G/A SNP genotyping, testicular volume evaluation by ultrasound scan, and semen analysis. A meta-analysis of the

-29 G/A SNP, evaluated in a previous study of the Sicilian population was done.

No genotype of the

2039 A/G SNP correlated with serum follicle-stimulating hormone (FSH) levels, testicular volume, sperm concentration, and total sperm count. In contrast, normozoospermic men with

-29 GG and

-29 GA genotypes had significantly lower sperm concentrations compared to men with the

-29 AA genotype. The other sperm parameters did not show any significant difference. The meta-analysis showed no significant difference in serum FSH levels, testicular volume, sperm concentration, and total sperm count between

-29 GG and

-29 AA in Sicilian men.
