Smart agriculture: utilizing machine learning and deep learning for drought stress identification in crops.

Plant stress reduction research has advanced significantly with the use of Artificial Intelligence (AI) techniques, such as machine learning and deep learning. This is a significant step toward sustainable agriculture. Innovative insights into the physiological responses of plants mostly crops to drought stress have been revealed through the use of complex algorithms like gradient boosting, support vector machines (SVM), recurrent neural network (RNN), and long short-term memory (LSTM), combined with a thorough examination of the TYRKC and RBR-E3 domains in stress-associated signaling proteins across a range of crop species.

The influence of wife abuse on women's reproductive choices inSouthern African Countries: Findings from a cross-sectional analysis of demographic and health surveys.

Understanding women's attitudes towards wife abuse and its effects on their reproductive choices is crucial for promoting gender equality in Southern Africa. However, a paucity of research has explored this relationship. Using IPUMS Demographic and Health Surveys data from 2011-2018 across eight Southern African nations, we analyzed 17,968 women's attitudes towards wife beating and their reproductive choices through a cross-sectional design and multilevel logistic regression models.

Four-Year Experience with Treatment Protocol for Odontogenic Necrotizing Fasciitis.

Odontogenic infections, irrespective of regional economic conditions, are a global health concern. Some cases escalate to severe levels, complicating treatment, endangering lives, and reducing positive outcomes. Necrotizing fasciitis is particularly lethal, with purulent collections and infection-derived gases spreading to distant regions.

Enhanced interpretable thyroid disease diagnosis by leveraging synthetic oversampling and machine learning models.

Thyroid illness encompasses a range of disorders affecting the thyroid gland, leading to either hyperthyroidism or hypothyroidism, which can significantly impact metabolism and overall health. Hypothyroidism can cause a slowdown in bodily processes, leading to symptoms such as fatigue, weight gain, depression, and cold sensitivity. Hyperthyroidism can lead to increased metabolism, causing symptoms like rapid weight loss, anxiety, irritability, and heart palpitations.

Carotenoids Intake and Cardiovascular Prevention: A Systematic Review.

: Cardiovascular diseases (CVDs) encompass a variety of conditions that affect the heart and blood vessels. Carotenoids, a group of fat-soluble organic pigments synthesized by plants, fungi, algae, and some bacteria, may have a beneficial effect in reducing cardiovascular disease (CVD) risk. This study aims to examine and synthesize current research on the relationship between carotenoids and CVDs.

Severe Malaria in Angola: The Clinical Profile and Disease Outcome Among Adults from a Low-Endemic Area.

Background/objectives: Severe malaria poses a significant public health concern in Angola, particularly among adults. This study assessed the clinical manifestations and outcomes of severe malaria in adult patients admitted to Hospital Central Dr. António Agostinho Neto of Lubango (HCL), Angola.

Association between maternal and child health care and neonatal death in Angola: a secondary analysis of Angola Demographic Health Survey 2015-16.

Background: Neonatal mortality has decreased in Angola; however, it remains high. Quality maternal and child health (MCH) care is key to improving neonatal survival. In Angola, however, the association between neonatal mortality and MCH care has not yet been investigated.

Virtual histopathology methods in medical imaging - a systematic review.

Virtual histopathology is an emerging technology in medical imaging that utilizes advanced computational methods to analyze tissue images for more precise disease diagnosis. Traditionally, histopathology relies on manual techniques and expertise, often resulting in time-consuming processes and variability in diagnoses. Virtual histopathology offers a more consistent, and automated approach, employing techniques like machine learning, deep learning, and image processing to simulate staining and enhance tissue analysis.

Virus Stability on Surfaces, in Bodily Fluids, in Wastewater and Different Environmental Conditions.

Information concerning the fundamental properties of a pathogen is essential at the beginning of an outbreak. Often, the fundamental properties of an emerging virus are unknown because the virus is new, as in the recent SARS-CoV-2 pandemic, or because the properties have not been investigated, as was the case during the West African Ebola virus epidemic and the Marburg virus epidemics in Angola and the Democratic Republic of the Congo. The amount of time that a virus can remain viable under various conditions is one of these fundamental properties.

Evaluation of Vaccines and Therapeutics Against Marburg Virus in Nonhuman Primate Models.

Marburg virus (MARV) has caused sporadic outbreaks of severe hemorrhagic fever in Africa in humans and nonhuman primates (NHPs) and has the potential to be used as a biological weapon. Currently, there are no licensed vaccines or therapeutics to respond to outbreaks or deliberate misuse. Vaccine and therapeutic efficacy testing against MARV requires animal models that accurately mimic human disease.

Evaluating Countermeasures Against Marburg Virus Using a Mouse Model.

Animal models are key tools for understanding Marburg virus (MARV) pathogenesis and evaluating novel countermeasures. Rodents, in particular, are useful model systems because they are inexpensive and easy to house and handle in maximum containment laboratories. Unfortunately, wild-type MARV, like other filoviruses, does not cause disease in immune-competent rodents and must first be adapted to the rodent host, typically through serial passaging.

Integrated studies on the epidemiology, clinical characteristics, seasonality, and genotype of dengue are limited. This study was conducted to determine recent trends in the molecular epidemiology, clinical features, and seasonality of dengue outbreaks.

Epidemiologic and genomic characterization of an outbreak of Rift Valley fever among humans and dairy cattle in northern Tanzania.

Background: A peri-urban outbreak of Rift Valley fever virus (RVFV) among dairy cattle from May through August 2018 in northern Tanzania was detected through testing samples from prospective livestock abortion surveillance. We sought to identify concurrent human infections, their phylogeny, and epidemiologic characteristics in a cohort of febrile patients enrolled from 2016-2019 at hospitals serving the epizootic area.

Methods: From September 2016 through May 2019, we conducted a prospective cohort study that enrolled febrile patients hospitalized at two hospitals in Moshi, Tanzania.

Revalidation of Enteromius crocodilensis (Fowler, 1934) from synonymy with the disjunctly distributed Enteromius argenteus (Günther, 1868) based on molecular and morphological evidence.

The rosefin barb, Enteromius argenteus, as currently described, is a freshwater fish with a distribution that is geographically separated and divided into the northern population in the Kwanza River system in Angola, and the southern population in the Inkomati River system in South Africa and Eswatini. Due to this disjunct distribution pattern, it is likely that the two populations represent distinct species. mtDNA sequence data and detailed examination of morphometric characters revealed considerable genetic (2.
