Heart Rate Variability in Hyperthyroidism
Cardiovascular effects of thyroid hormones may be measured through heart rate variability (HRV). Hyperthyroidism is associated with a decreased HRV, which may be explained by the effect of thyroid hormones and thyroid-stimulating hormone (TSH). The increased sympathetic and decreased parasympathetic activity may have clinical implications.

Genetics of Amyotrophic Lateral Sclerosis
Amyotrophic lateral sclerosis (ALS) is the most frequent motor neuron disease and a neurodegenerative disorder, affecting the upper and/or lower motor neurons. Notably, it invariably leads to death within a few years of onset. Although most ALS cases are sporadic, familial amyotrophic lateral sclerosis (fALS) forms 10% of the cases. In 1993, the first causative gene (SOD1) of fALS was identified. With rapid advances in genetics, over fifty potentially causative or disease-modifying genes have been found in ALS so far. Accordingly, routine diagnostic tests should encompass the oldest and most frequently mutated ALS genes as well as several new important genetic variants in ALS.

Adipose Tissue and Metastatic Cascade
Obesity is a modern health problem that has reached pandemic proportions. It is an established risk factor for carcinogenesis, however, evidence for the contribution of adipose tissue to the metastatic behavior of tumors is also mounting. Over 90% of cancer mortality is attributed to metastasis and metastatic tumor cells must communicate with their microenvironment for survival. Many of the characteristics observed in obese adipose tissue strongly mirror the tumor microenvironment. Thus in the case of prostate, pancreatic and breast cancer and esophageal adenocarcinoma, which are all located in close anatomical proximity to an adipose tissue depot, the adjacent fat provides an ideal microenvironment to enhance tumor growth, progression and metastasis. Adipocytes provide adipokines, fatty acids and other soluble factors to tumor cells whilst immune cells infiltrate the tumor microenvironment.

Point-of-Care Ultrasound in DVT Diagnosis
Acute lower extremity proximal deep venous thrombosis (DVT) requires accurate diagnosis and treatment in order to prevent embolization and other complications. Point-of-care ultrasound (POCUS), a clinician performed, and clinician interpreted bedside ultrasound examination has been increasingly used for DVT evaluation mainly in the urgent and critical care setting, but also in the ambulatory clinics and the medical wards.

Beneficial effects of Glycine in the Organism
Glycine is an amino acid that our bodies can produce naturally, so we don't necessarily need to get it from our diet. Nevertheless, it plays a vital role in various functions throughout our entire body. Glycine interacts with specific receptors and transporters found in many different types of cells, which allows it to have important effects on our health. One of the most fascinating things about glycine is its potential to reduce inflammation in our body. Researchers have conducted many studies focusing on this aspect. Glycine has been shown to decrease pro-inflammatory molecules called cytokines, which are responsible for promoting inflammation. Additionally, it can lower the levels of free fatty acids, which are sometimes linked to inflammation in certain situations. Moreover, glycine seems to positively influence how our body responds to insulin, which is crucial for maintaining stable blood sugar levels. It also appears to bring about other beneficial changes in our body, although scientists are still investigating the specific details of these effects. Glycine is a remarkable amino acid that offers many health benefits, especially in terms of reducing inflammation and possibly enhancing how our bodies respond to insulin. It's fascinating because it is present throughout our entire body, and we can obtain it through our diet or nutraceuticals, affecting our health in various ways. Scientists continue to study glycine to unlock its full potential and better understand its role in supporting our well-being.

Connexins in Cancer
The expression, localization, and function of connexins, the protein subunits that comprise gap junctions, are often altered in cancer. In addition to cell–cell coupling through gap junction channels, connexins also form hemichannels that allow communication between the cell and the extracellular space and perform non-junctional intracellular activities. Historically, connexins have been considered tumor suppressors; however, they can also serve tumor-promoting functions in some contexts. Here, we review the literature surrounding connexins in cancer cells in terms of specific connexin functions and propose that connexins function upstream of most, if not all, of the hallmarks of cancer. The development of advanced connexin targeting approaches remains an opportunity for the field to further interrogate the role of connexins in cancer phenotypes, particularly through the use of in vivo models. More specific modulators of connexin function will both help elucidate the functions of connexins in cancer and advance connexin-specific therapies in the clinic.

The History of Blood Vessel Anastomosis
Surgical technique and technology frequently coevolve. The brief history of blood vessel anastomosis is full of famous names. While the techniques pioneered by these surgeons have been well described, the technology that facilitated their advancements and their inventors deserve recognition. The mass production of laboratory microscopes in the mid-1800s allowed for an explosion of interest in tissue histology. This improved understanding of vascular physiology and thrombosis laid the groundwork for Carrel and Guthrie to report some of the first successful vascular anastomoses. In 1916, McLean discovered heparin. Twenty-four years later, Gordon Murray found that it could prevent thrombosis when performing end-to-end anastomosis. These discoveries paved the way for the first-in-human kidney transplantations. Otolaryngologists Nylen and Holmgren were the first to bring the laboratory microscope into the operating room, but Jacobson was the first to apply these techniques to microvascular anastomosis. His first successful attempt in 1960 and the subsequent development of microsurgical tools allowed for an explosion of interest in microsurgery, and several decades of innovation followed.

The Blood-Brain Barrier
Blood-brain barrier (BBB) integrity is essential to maintaining brain health. Aging-related alterations could lead to chronic progressive leakiness of the BBB, which is directly correlated with cerebrovascular diseases. Indeed, the BBB breakdown during acute ischemic stroke is critical.

Mitochondria in Exercise-Induced Neuroprotection
Regular exercise is associated with pronounced health benefits. The molecular processes involved in physiological adaptations to exercise are best understood in skeletal muscle. Enhanced mitochondrial functions in muscle are central to exercise-induced adaptations. However, regular exercise also benefits the brain and is a major protective factor against neurodegenerative diseases, such as the most common age-related form of dementia, Alzheimer’s disease, or the most common neurodegenerative motor disorder, Parkinson’s disease.
