Anthelmintic resistance against gastrointestinal nematodes: an emerging threat in cattle farms in Bangladesh.

Anthelmintic resistance (AR) is a major problem in the profitable production of livestock. Therefore, this study evaluated AR status in cattle farms at Mymensingh Sadar using in vivo, fecal egg count reduction test (FECRT) and in vitro, egg hatch assay (EHA) techniques. For this, ten cattle farms and forty animals from individual farms with more than 200 eggs per gram (EPG) of feces were selected by employing the McMaster technique.

Efficacy of Routinely Used Anticoccidials Against Eimeria tenella Field Isolates in Chicken: Bangladesh Perspective.

To evaluate anticoccidial drug efficacy against Eimeria tenella in chicken, seven different field isolates were experimented with in battery cages with five commonly used anticoccidials as manufacturer doses, like amprolium (1 g/L), maduramicin (5 ppm), sulphaclozine (2 g/L), toltrazuril (25 mg/L) and amprolium + sulphaquinoxaline (1 g/L). One hundred twelve birds of the Ross strain were raised on a rice husk-littered floor for the first 11 days with ad libitum water and anticoccidial-free feed, facilitating a standard environment. On Day 12, the birds were divided into seven experimental groups with 16 birds each, and the respective anticoccidials were started for Groups I-V and continued up to 7 days post-infection.

A deep learning model for classifying left ventricular enlargement for both transthoracic echocardiograms and handheld cardiac ultrasound.

Aims: To develop a deep learning model that: (i) utilizes transthoracic echocardiography (TTE) clips to detect left ventricular (LV) enlargement without being provided information regarding a patient's sex and body size; and (ii) can be accurately applied to clips acquired using either standard comprehensive TTE or handheld cardiac ultrasound (HCU).

Methods And Results: Using retrospective TTE data (training: 8722 patients; internal validation: 468 patients), we developed a deep learning model that estimates a patient's end-diastolic LV volume (indexed to body surface area and normalized across the sexes), and then thresholds this estimate to perform the following classifications: (1) normally sized LV vs. ≥ mild LV enlargement; (2) normal/mildly enlarged LV vs.

However, the association between SR and CPP and chronic stable HF with and without pulmonary hypertension (PH) as well as PH alone have not been previously studied.

Leveraging Comprehensive Echo Data to Power Artificial Intelligence Models for Handheld Cardiac Ultrasound.

Objective: To develop a fully end-to-end deep learning framework capable of estimating left ventricular ejection fraction (LVEF), estimating patient age, and classifying patient sex from echocardiographic videos, including videos collected using handheld cardiac ultrasound (HCU).

Patients And Methods: Deep learning models were trained using retrospective transthoracic echocardiography (TTE) data collected in Mayo Clinic Rochester and surrounding Mayo Clinic Health System sites (training: 6432 studies and internal validation: 1369 studies). Models were then evaluated using retrospective TTE data from the 3 Mayo Clinic sites (Rochester, n=1970; Arizona, n=1367; Florida, n=1562) before being applied to a prospective dataset of handheld ultrasound and TTE videos collected from 625 patients.

Fine-Tuning Large Language Models for Specialized Use Cases.

Large language models (LLMs) are a type of artificial intelligence, which operate by predicting and assembling sequences of words that are statistically likely to follow from a given text input. With this basic ability, LLMs are able to answer complex questions and follow extremely complex instructions. Products created using LLMs such as ChatGPT by OpenAI and Claude by Anthropic have created a huge amount of traction and user engagements and revolutionized the way we interact with technology, bringing a new dimension to human-computer interaction.

Snapshot artificial intelligence-determination of ejection fraction from a single frame still image: a multi-institutional, retrospective model development and validation study.

Background: Artificial intelligence (AI) is poised to transform point-of-care practice by providing rapid snapshots of cardiac functioning. Although previous AI models have been developed to estimate left ventricular ejection fraction (LVEF), they have typically used video clips as input, which can be computationally intensive. In the current study, we aimed to develop an LVEF estimation model that takes in static frames as input.

Characteristics, Contamination Levels, and Ecosystem Risk Assessment of Microplastics in Surface Water of a Highly Urbanized River from a Developing Country.

Microplastic (MP) contamination poses significant risks to ecosystems and human health. However, the absence of standardized protocols, detailed polymer identification, and sources identification hinders the development of targeted mitigation strategies, particularly in developing nations. There is a scarcity of comprehensive data on MP distribution, sources, and transport mechanisms in freshwater environments.

A novel chemokine binding protein 1-like gene is vital for the blood pool development and engorgement of the hard tick Haemaphysalis longicornis.

Tick saliva modulates host responses during a blood feeding process. We identified a novel chemokine binding protein 1-like (HLCBP1-like) gene from the salivary glands of the Asian longhorned tick, Haemaphysalis longicornis. The HLCBP1-like protein, lacking a well-defined conserved domain, showed structural similarity to evasin, a chemokine binding protein from the brown dog tick, Rhipicephalus sanguineus.

Pyoverdine binding aptamers and label-free electrochemical detection of pseudomonads.

Pyoverdines are iron-chelating siderophores employed by various pseudomonads to promote their growth in iron-limited environments, facilitating both beneficial and detrimental interactions with co-inhabiting microbes or hosts, including plants and animals. The fluorescent pseudomonads produce fluorescent pyoverdines comprised of a conserved central chromophore and a unique strain-specific peptidic side chain produced by non-ribosomal peptide synthetases. Pyoverdine Pf5 (PVD-Pf5) is produced by Pf-5, a species known for supporting plant growth and its involvement in plant pathogen control.
