Recent findings indicate that the microbiota is involved in the development of lung cancer by inducing inflammatory responses and generating genome damage. This study aimed to compare sputum microbiomes from the mouth and oropharynx in non-small cell lung carcinoma (NSCLC) patients. A second goal was to search for bacterial taxonomic units that behave differently in the microbiome of NSCLC patients and healthy subjects. In the study, the taxonomic composition of the sputum and oropharyngeal microbiomes of 23 male p [...]

To increase power level in an autonomous microgrid, higher voltage is necessary. In this paper, detailed Matlab/Simulink modeling of a microgrid operated at medium-voltage level and at constant frequency has been conducted. Modified boost converter and medium-frequency transformer isolated DC/DC converter are adopted for both solar energy and wind energy harnessing in order for them to be connected with the microgrid. This paper further adopted a differential evolution (DE)-based method to carry out load flow analy [...]

Tomato (Solanum lycopersicum L.) is the largest vegetable crop produced and consumed in the world. Tomatoes are a top source of Vitamin A and C, contain more dietary fibre, beta-carotene, iron, lycopene, magnesium, niacin, potassium, phosphorus, riboflavin, and thiamine. Tomatoes have a limited shelf life in ambient conditions and are highly perishable. It creates glut during the production season and becomes scanty during the off-season. Short shelf life, coupled with inadequate processing facilities results in he [...]

Acute rejection (AR) is one of the main predictors of long-term survival of allograft. The development of noninvasive diagnostic biomarkers of AR is an unmet need for the timely detection. This study aimed to identify novel detective biomarkers of AR by analyzing the urine proteome profile of transplant patients. Forty-two transplant patients including 30 biopsy-proven AR patients (including antibody and T-cell mediated rejection) and 12 transplant patients with stable renal function (control group) were enrolled.

Background: The association between hepatitis C virus (HCV) infection and oral lichen planus (OLP), an extrahepatic manifestation, is well known. There are still patients with viral liver disease in this country who are not receiving appropriate treatment. This prospective study aimed to evaluate the prevalence of OLP and untreated hepatitis virus infection in patients who visited dental clinics in Ehime prefecture, in western Japan. Methods: Patients who visited 35 dental clinics in Japan from March 2018 to June 2 [...]

This study examined the correlates of change in the depressed state among people aged 65 and older during the SARS-CoV-2 pandemic, particularly the effects of crucial pandemic-related variables. Data were drawn from the longitudinal Survey of Health, Ageing and Retirement in Europe (SHARE), including information obtained from two special pandemic-related telephone interviews (N = 18, 266). The analysis regressed depressed state soon after the outbreak (T1) and again a year later (T2), on four pandemic-related varia [...]

Because of climate change, greenhouse gas (GHG) emissions have increased, leading to the implementation of energy transition policies. Countries have adopted the Paris Agreement to curb the effects of climate change. The emergence of COVID-19 in 2020 led to the application of different measures to stop its transmission. This study evaluated the effects of COVID-19-related restrictions (such as quarantine and mobility restriction) in Chile during the first wave on compliance with the country's energy transition poli [...]

Stroke survivors often receive spousal support for post-stroke impairments. The quality of spousal caregiving and couples’ wellbeing can suffer from post-stroke relationship changes and caregiver burden. Because swallowing impairment (dysphagia) is common post-stroke and spouses providing dysphagia care may experience burden, it is also important to explore whether relationship changes post-stroke are associated with dysphagia outcomes. The purpose of this study was to describe stroke survivor-spouse relationships [...]
