Summary: Approximately 20%-30% of plant and animal species are at risk of extinction by the end of the 21st century due to climate change, impacting the distribution and survival of animal species relying on plants. Climate change is projected to alter species composition and distribution in the forested landscapes of the northern highlands of Pakistan, potentially affecting the Asiatic black bear.

Summary: Studying activity patterns is crucial for understanding animals' behavior adaptation based on habitat conditions. Monitoring Asiatic black bear activity patterns in the Qinling Mountains, researchers found higher activity levels from June to October, with a shorter hibernation period. Bears were mainly active during the daytime in spring and summer, while more active at twilight in autumn. Food preferences and availability due to regional climate conditions are suggested as factors influencing these activity patterns.

Summary: This study found that treatment with hibernating bear serum had an effect on protein metabolism in human skeletal muscle cells. After treatment with hibernating bear serum, the total protein content in the cells significantly increased, while the expression of MuRF1 protein decreased and Akt/FOXO3a signaling was activated. In addition, increased levels of IGF-1 were observed in the hibernating bear serum.

Summary: The study characterized the amino acid and acylcarnitine profiles of black bears in Mexico and identified metabolites with age-related variability, which could serve as potential biomarkers for early diagnosis of metabolic disorders in endangered species. This is the first study of its kind in black bears and the findings can be used as reference for future studies.

Summary: The role of point-of-care ultrasound (POCUS) has become vital in patient management, and the availability of small-sized hand-held ultrasound devices (HUDs) has further expanded its applications, especially in the context of COVID-19. This review focuses on the technology, usefulness, feasibility, and clinical applications of HUD for echocardiogram assessment in COVID-19 patients.

Summary: Cardiac adaptation to conditioning in horses was evaluated through empirical training based on trainers' experience. The study involved twelve purebred Arabian horses, aged 28.42 +/- 3.75 months, which underwent treadmill conditioning for six weeks. The results showed increased velocity and improvements in cardiac parameters, indicating the safe and efficient nature of the training program.

Summary: This study aims to determine the true incidence of arrhythmias, especially atrial fibrillation, in patients with obstructive sleep apnoea using implantable loop recorders (ILRs). It also intends to assess cardiac autonomic function and explore cardiovascular outcomes. The study will involve 200 patients who will be randomized to receive either standard care alone or standard care plus ILR and Holter monitoring. The primary objective is to compare arrhythmia detection over 3 years between the two groups. The study has been approved by the ethics committee and plans to publish the findings in peer-reviewed journals.

Summary: The study validated three techniques for estimating epicardial and volumetric conduction velocity, showing accurate and reliable results for examining changes in propagation in the heart. Results indicated close agreement between reconstructed and ground truth activation times, with calculated CVs also matching actual values closely.

Summary: Accidental bromine spills are common and pose a risk of potential terrorist attacks due to its large industrial stores. The mechanisms of bromine toxicity and effective therapeutic strategies remain unknown. Research findings suggest that inhaled bromine can cause deleterious cardiac manifestations, leading to delayed cardiac effects and chronic dysfunction. Further studies are needed to evaluate therapies for bromine-induced cardiac damage.

Summary: The study found that cardiac rehabilitation has beneficial effects in heart-failure patients who received LVAD instead of HTx, with short-term outcomes similar to HTx patients and no deterioration in LVAD patients up to 12 months after discharge.

Summary: The aim of this study was to investigate the underlying mechanisms of atrial remodeling in cardiac implanted electronic device (CIED)-detected atrial high-rate episodes (AHRE). Structural and functional characteristics of both atria were assessed using cardiac computed tomography and strain echocardiography. It was found that as the duration of AHRE increased, there was an increasing worsening of left atrial volume, atrial precontraction volume, minimal volume, emptying fraction, and atrial longitudinal/contractile strain. Patients with AHRE >6 hours showed enlarged biatrial volumes, impaired left atrial reservoir and pump function, and reduced atrial longitudinal/contractile strain. These changes in atrial structure and function may serve as surrogate imaging markers for stroke risk assessment in patients with CHA2DS2-VASc ≥ 2 and AHRE.

Summary: Clinical auditory physiological measures provide specificity for diagnosing hearing impairments, but have limitations in detecting specific sites of lesion and subtle cochlear damage. A normative set of physiological measures using ABRs and DPOAEs in macaque monkeys is presented, serving as a crucial baseline for improving diagnostics.

Summary: The objective of this study is to investigate the feasibility of using heart rate characteristics to estimate atrial fibrillatory rate (AFR) in patients with atrial fibrillation (AF). A mixed model approach was used to analyze the data and correct for other factors such as previous ablations and episode duration.
