The goal of this study was to examine the influence of the COVID-19 pandemic, including public health measures (mitigation and containment efforts), on new onset mental health diagnoses by age group. This study was a longitudinal retrospective cohort study. Data on new mental health diagnoses were extracted from the University of California Health System Electronic Health Records (EHR) that contained five academic health centers in California.

Baculoviruses have been extensively studied for their potential in microbial pest control, but the mechanisms behind their mode of action still need to be addressed. Here we report differential expression of a cellular miRNA, Sfr-miR-184, from Sf9 cells in response to Autographa californica multicapsid Nucleopolyhedrovirus (AcMNPV) infection. Our results showed that Sfr-miR-184 is down-regulated in AcMNPV-infected cells but not with UV-inactivated virus.

Background: Wolbachia are widespread intracellular bacteria in insects that often have high rates of spread due to their impact on insect reproduction. These bacteria may also affect the mating behavior of their host with impacts on the fitness of host progeny. In this study, we investigated the impact of Wolbachia on a preference for mating with young or old males in the parasitoid wasp Habrobracon hebetor.

DNA methylation is an epigenetic process that involves the chemical modification of DNA, leading to the regulation of its transcriptional activity. It is primarily known for the addition of methyl groups to cytosine in DNA. The whitefly Bemisia tabaci is a polyphagous pest insect and a vector that is responsible for transmitting numerous plant viruses, resulting in significant economic losses in agricultural crops globally.

Non-small cell lung cancer (NSCLC) has constituted over 80% of the lung cancer population with a poor prognosis. Over the past decade, immunotherapy has been constructed in the enlargement of immune checkpoint inhibitors as a promising approach for NSCLC treatment. Evading the immune system using the PD-1/PD-L1 axis is an intelligent way for cancers, and T cells cannot respond fully and confront cancer.

Background: The production of bovine theileriosis vaccine involves in vitro cultivation of schizont-infected cell lines. Fetal bovine serum (FBS) is commonly used in animal cell culture, including the cell line. However, we aimed to reduce the amount of serum needed for cell culture by modifying the Stoker culture medium with supplements such as excretion factor and serum substitutes.

Following pathogen infection in a host, extensive changes occur in the host's gene expression pattern to suppress infection and increase the chance of host survival. Likewise, many pathogens have evolved to evade/suppress host immunity and increase their survival within the host. In this study, we assessed the NF-κB (Imd and Toll) essential gene expression response of Helicoverpa armigera to an entomopathogenic Serratia marcescens and non-pathogenic Escherichia coli.

Background: Pregnancy and childbirth may provoke various emotional responses in expectant fathers including excessive fear of childbirth. It is not unreasonable to assume that fear of contracting the virus during the COVID-19 pandemic, may have intensified fathers' fear of childbirth. This study aims to determine the mediating role of the expectant mothers' fear of childbirth in the relationship between expectant fathers' fear of COVID-19 and their fear of childbirth.

California was the first state to implement statewide public health measures, including lockdown and curfews, to mitigate transmission of SARS-CoV-2. The implementation of these public health measures may have had unintended consequences related to mental health for persons in California. This study is a retrospective review of electronic health records of patients who sought care in the University of California Health System to examine changes in mental health status during the pandemic.

Background: Physical activity (PA) confers numerous benefits to health and health care costs, yet most adults are not meeting recommended PA guidelines. Stress may be a factor that influences PA behavior. Research investigating the impact of stress on PA has yielded inconsistent findings.

Background: Application of insect growth regulators (IGR) is a good option for insect pest management because of their fewer adverse effects on humans and domestic animals. These compounds are capable of interfering with normal growth and development by mimicking the actions of hormones such as juvenile hormone (JH) or ecdysone. The effect of JH and its analogs on some aspects of insect immunity has been determined, yet their possible effects on antiviral immunity response has not been investigated yet.

The endocrine system modulates several physiological functions such as development and metamorphosis in insects. The normal growth and development of insects is interfered with insect growth regulators (IGRs), which act as mimics of insect hormones like juvenile hormone (JH) and ecdysone hormone. The effects of JH and its analogs on systemic immunity have been identified.

Continuous monitoring of blood pressure (BP) can help individuals manage their chronic diseases such as hypertension, requiring non-invasive measurement methods in free-living conditions. Recent approaches fuse Photoplethys-mograph (PPG) and electrocardiographic (ECG) signals using different machine and deep learning approaches to non-invasively estimate BP; however, they fail to reconstruct the complete signal, leading to less accurate models. In this paper, we propose a cycle generative adversarial network (CycleGAN) based approach to extract a BP signal known as ambulatory blood pressure (ABP) from a clean PPG signal.

Article Synopsis
  • Foot and mouth disease (FMD) is a highly contagious illness affecting cloven-hoofed animals and is prevalent in Iran, where outbreaks occur year-round.
  • A study analyzed FMD vaccine effectiveness using data from outbreaks and vaccination records in cattle farms from January 2017 to March 2019, involving a case-control approach.
  • The results showed medium vaccine protection, with effectiveness highest in farms using a specific commercial vaccine, indicating the need for improved vaccination coverage, especially in industrial and semi-industrial farms to reduce virus circulation.

Background: MicroRNAs (miRNAs) are small regulatory non-coding RNAs that are involved in a variety of biological processes such as immunity, cell signaling and development by regulating gene expression. The whitefly Bemisia tabaci is a polyphagous vector that transmits many plant viruses causing economic damage to crops worldwide. In this study, we characterized and analyzed the expression of the miRNA core genes Argonaute-1 (Ago1) and Dicer-1 (Dcr1) in B.

The aim of this study was to find the direct economic losses due to the three viral causes of the avian respiratory syndrome, including Newcastle disease (ND), H9N2 influenza, and infectious bronchitis (IB) in stamped-out broiler farms during 2016-2017 across the country. This study was carried out on the information on cross-sectional monitoring in the years 2016-2017. The statistical society of the study was all the active broiler farms of the country stamped out due to respiratory syndrome.

Article Synopsis
  • COVID-19 has significantly impacted the world, particularly in the U.S., which has the highest number of cases and where patients with acute respiratory distress syndrome (ARDS) face severe health risks.
  • Research methods for assessing COVID-19 and ARDS typically rely on clinical settings and symptoms, which can be ineffective, whereas vital signs like heart rate and blood pressure show potential for early detection of respiratory diseases.
  • This study utilizes vital signs from a large sample of ARDS patients to develop a deep learning model that accurately distinguishes between COVID-19 infected and non-infected individuals, suggesting that everyday vital sign monitoring could allow for early identification of the virus outside of clinical environments.
