Collagen α3 (IV) chains are one of the major constituent components of the basement membrane in the mammalian testis. Studies have shown that biologically active fragments, such as noncollagenase domain (NC1)-peptide, can be released from the C-terminal region of collagen α3 (IV) chains, possibly through the proteolytic action of metalloproteinase 9 (MMP9). NC1-peptide was shown to promote blood-testis barrier (BTB) remodeling and fully developed spermatid (e.g., sperm) release from the seminiferous epithelium because this bioactive peptide was capable of perturbing the organization of both actin- and microtubule (MT)-based cytoskeletons at the Sertoli cell-cell and also Sertoli-spermatid interface, the ultrastructure known as the basal ectoplasmic specialization (ES) and apical ES, respectively. More importantly, recent studies have shown that this NC1-peptide-induced effects on cytoskeletal organization in the testis are mediated through an activation of mammalian target of rapamycin complex 1/ribosomal protein S6/transforming retrovirus Akt1/2 protein (mTORC1/rpS6/Akt1/2) signaling cascade, involving an activation of cell division control protein 42 homolog (Cdc42) GTPase, but not Ras homolog family member A GTPase (RhoA), and the participation of end-binding protein 1 (EB1), a microtubule plus (+) end tracking protein (+TIP), downstream. Herein, we critically evaluate these findings, providing a critical discussion by which the basement membrane modulates spermatogenesis through one of its locally generated regulatory peptides in the testis.
The COVID-19 outbreak has overwhelmed and altered health care systems worldwide, with a substantial impact on patients with chronic diseases. The response strategy has involved implementing measures like social distancing, and care delivery modalities like telemedicine have been promoted to reduce the risk of transmission.

The aim of this study was to analyze the benefits of using telemedicine services for patients with chronic liver disease (CLD) at a tertiary care center in Italy during the COVID-19-mandated lockdown.

From March 9 to May 3, 2020, a prospective observational study was conducted in the Liver Unit of the University Hospital of Naples Federico II to evaluate the impact of (1) a fully implemented telemedicine program, partially restructured in response to COVID-19 to include video consultations; (2) extended hours of operation for helpline services; and (3) smart-working from home to facilitate follow-up visits for patients with CLD while adhering to social distancing regulations.

Duringity to be in contact with physicians while respecting social distancing rules.
Technological communication methods such as telephone calls and video calls can help prevent social isolation and loneliness in frail older adults during confinement.

Our objectives were to determine which virtual communication method (ie, telephone call or video call) was preferred by confined older hospital patients and nursing home residents and the variables influencing this preference.

The TOVID (Telephony Or Videophony for Isolated elDerly) study was a cross-sectional study that was designed to examine the preference between telephone calls and video calls among frail older adults who were either hospitalized in a geriatric acute care unit or institutionalized in a long-term care and nursing home during the COVID-19 confinement period.

A total of 132 older people were surveyed between March 25 and May 11, 2020 (mean age 88.2 years, SD 6.2); 79 (59.8%) were women. FDA approved Drug Library Patients hospitalized in the geriatric acute care unit were more able to establish communication independently than residents institutamong long-term care and nursing home residents when they were given assistance to establish communication.

Indonesia is the only country in the Asia Pacific region where the incidence of HIV is still on the rise, and its prevalence is extremely high among the key populations such as men who have sex with men, transgender women, and people who inject/use drugs. Mobile health (mHealth) apps provide an innovative platform for delivering tailored HIV prevention and care among these populations more efficiently than possible through the direct face-to-face approach.

The aim of this study was to assess the role of a peer-customized mobile app based on the principle of self-learning for improving HIV prevention knowledge and access to health services among men who have sex with men, transgender women (known as Waria in Indonesia), and people who use drugs in Indonesia.

A prospective intervention cohort study was conducted among the key populations in five provinces of Indonesia (Jakarata, West Java, East Java, Special Region of Yogyakarta, and Bali). The data were evaluated using a pre-post assessment survey conducommunity. There is a need to scale up such interventions for efficacy testing in a larger population to provide evidence for national-level mHealth programs addressing HIV.
This one-of-a-kind mHealth intervention with an mHealth app as a self-learning tool is effective in increasing HIV-related knowledge and behavior, and access to services with strong acceptability by the community. There is a need to scale up such interventions for efficacy testing in a larger population to provide evidence for national-level mHealth programs addressing HIV.Electron microscopy is a powerful tool for visualizing the shapes of sub-nanometer objects. However, Contrast Transfer Function (CTF) principally restricts lower frequency components in the image. To overcome this problem, phase-plate techniques have been proposed and currently Hole Free Phase Plate (HFPP) and Volta Phase Plate (VPP) are widely used especially for biological specimens to retrieve low frequency information of the sample's potential distributions. In this report, we have developed a new phase-contrast scanning transmission electron microscope (STEM) in which a probe beam including side robes is formed with an amplitude Fresnel zone plate (FZP) and the interference patterns produced by the zero and first order diffracted waves generated by the FZP are detected. We name it FZP Phase Contrast STEM (FZP-PC-STEM) hereinafter. The amplitude FZP was manufactured by using focused ion beam (FIB) equipment, and the diffraction data were collected by using diffraction imaging technique. The validity of our proposed optical model was confirmed by comparing experimental and simulated images.
