Strength and Conditioning Programs to Increase Bat Swing Velocity for Collegiate Baseball Players.

Bat swing velocity (BSV) is an imperative element of a successful baseball hitting performance. This study aimed to investigate the anthropometric and physiological variables associated with BSV and explore strength and conditioning programs to increase BSV in collegiate baseball players. Seventy-eight collegiate baseball players (mean age ± SD, 19.

Pattern recognition receptors involved in the immune system of hagfish (Eptatretus burgeri).

The initial defense against invading pathogenic microbes is the activation of innate immunity by binding of pattern recognition receptors (PRRs) to pathogen associated molecular patterns (PAMPs). To explain the action of PRRs from hagfish, one of the extant jawless vertebrates, we purified the GlcNAc recognition complex (GRC) from serum using GlcNAc-agarose. The GRC comprises four proteins of varying molecular masses: 19 kDa, 26 kDa, 27 kDa, and 31 kDa.

A graph convolutional network for predicting COVID-19 dynamics in 190 regions/countries.

Introduction: Coronavirus disease (COVID-19) rapidly spread from Wuhan, China to other parts of China and other regions/countries around the world, resulting in a pandemic due to large populations moving through the massive transport hubs connecting all regions of China railways and a major international airport. COVID-19 will remain a threat until safe and effective vaccines and antiviral drugs have been developed, distributed, and administered on a global scale. Thus, there is urgent need to establish effective implementation of preemptive non-pharmaceutical interventions for appropriate prevention and control strategies, and predicting future COVID-19 cases is required to monitor and control the issue.

Acute effects of ambient temperature on lung function of a panel of school children living in Dhaka, Bangladesh.

Introduction: Short-term exposure to ambient temperature plays a significant role in human health. However, studies examining ambient temperature and lung function are scarce in locations with a tropical environment. To address this research gap, the current study investigated the effects of short-term ambient temperature on lung function in children and seasonal variation in this association in Dhaka, Bangladesh.

Effect of Ambient Temperature on Daily Nebulized Asthma Hospital Visits in a Tropical City of Dhaka, Bangladesh.

The acute effect of temperature on asthma morbidity in Bangladesh is not well understood. As climate varies extensively in different parts of the world, the relation between temperature and asthma might also differ. We investigated the association between temperature and asthma-related hospital visits in the tropical city of Dhaka.

Effects of Short-term Exposure to Ambient Particulate Matter on the Lung Function of School Children in Dhaka, Bangladesh.

Background: Ambient particulate pollution may adversely affect children's lung function. However, evidence on this association remains scarce in Asia despite this region having the greatest burden of disease due to air pollution.

Objectives: To investigate the effect of short-term exposure to ambient particulate matter (PM) on the lung function of school children in Dhaka city, Bangladesh.

Short-term exposure to ambient particulate matter and emergency ambulance dispatch for acute illness in Japan.

Short-term exposure to air pollution may be linked to negative health outcomes that require an emergency medical response. However, few studies have been undertaken on this phenomenon to date. The aim of this study therefore was to examine the association between short-term exposure to ambient suspended particulate matter (SPM) and emergency ambulance dispatches (EADs) for acute illness in Japan.

Detection of Japanese eel endothelial cells-infecting virus in Anguilla japonica elvers.

Japanese eel endothelial cells-infecting virus (JEECV) has spread in eel farms and caused serious economic loss. In this study, we examined the prevalence of JEECV infection in 100 wild Japanese eel (Anguilla japonica) elvers caught from Yamaguchi prefecture, Japan, using quantitative PCR and conventional PCR. Total genomic DNA was obtained from the cranial quarter of the body in 70 of 100 eels and from the gill in the remaining.

Relationship between the risk for a shrimp allergy and freshness or cooking.

Tropomyosins are defined as risk factors for shrimp allergy. However, their concentration in different preparations has not been clarified. We quantified the tropomyosin concentration in shrimp meat, which was cooked using several methods or was stored under various conditions.

Histopathological and ultrastructural features of Koi herpesvirus (KHV)-infected carp Cyprinus carpio, and the morphology and morphogenesis of KHV.

Epizootics of Koi herpesvirus (KHV) cause mass mortalities in koi carp and common carp worldwide. We used a newly developed 'per-gill infection' procedure with live KHV, and then conducted detailed histopathological and ultrastructural studies of KHV-infected cells including an examination of the morphology and morphogenesis of KHV. The primary target of KHV was respiratory epithelial cells of the gill lamellae, and release of virions from infected epithelial cells resulted in a systemic infection affecting the kidney, spleen, heart, brain and liver.
