Thyroid transcription factor 1 (TTF-1) is a nuclear polypeptide and a tissue-restricted member of the homeobox protein family that, when attached to DNA, plays a crucial role in regulating the expression of select genes during early embryonic development of the thyroid, lung, and brain. As often happens, the initial enthusiasm for the diagnostic value of TTF-1 as a selective immunohistochemical marker of lung and thyroid tumors began to dwindle, due to its detection in tumors arising from other organs. TTF-1-expres [...]

Identifying and addressing ethical issues in the care of older adults can be complex and challenging in clinical settings. This article reviews specific ethical principles including autonomy, beneficence, non-maleficence, dignity, and justice, and explores them in the context of interprofessional geriatric care. Situations and related ethical components such as treatment in intensive care units, end-of-life care, dementia care, and aging with advancing technology are included. Case scenarios for each principle or s [...]

The widespread usage of various wireless equipment in many facets of life has significantly contributed to the severe pollution caused by electromagnetic radiation. Thankfully, scientists have created materials that can absorb microwave radiation and convert dangerous electromagnetic waves into other forms of energy, including heat energy. Many recent investigations have been published regarding developing materials that absorb microwaves with different constituents, morphologies, and architectures. Microwave-absor [...]

Newborn screening (NBS) for Severe Combined Immunodeficiency (SCID) has been successfully implemented in all 50 United States and Puerto Rico from 2008-2018. This life-saving screening tool has drastically improved overall survival of babies diagnosed with SCID from 74% to 96%. TREC is a stable, circular DNA molecule that is produced during the process of T-cell receptor (TCR) rearrangement and is the target of the quantitative PCR screen on Guthrie cards. Low TRECs are a marker of low naive T cell numbers. This ne [...]

Furcal perforation management in root canal retreatment is often challenging as the outcome of the perforation sealing depends on several parameters. The recent introduction of several bioactive cements and magnification systems has made the sealing of perforations easier and the outcome more predictable. This study highlights the clinical outcomes of furcal perforation management in root canal retreatment using biodentine.

We report the case of a 30-year-old male with significant obesity (body mass index 47 kg/m2) with co-existing moderate obstructive sleep apnoea, hypertension, hypercholesteremia and hypogonadotropic hypogonadism, who was treated with a very-low-energy diet (VLED) and lifestyle modification programme for 12 months. The patient lost weight throughout the entire treatment period (average weight loss was 2.1 kg/week, for a total of 42.7 kg), and showed marked improvement in co-morbidities and no adverse effects. This c [...]

Gait speed has been correlated to quality of life and has been called the sixth vital sign. The purpose of this study was to understand the factors that comprise fast and comfortable gait speed. 90 older adults provided demographic, cognitive, and functional performance data. Hierarchical linear regression models revealed predictors for comfortable gait speed to be lower-extremity strength ( B = 1.13, β = 0.233, P< .05), comorbid health ( B = −2.95, β = −0.22, P < 0.05), and gender( B = [...]

Background: Promoting a good quality of life for the oldest members of society has become a top priority as evidenced in UK policy. The ‘household’ model is a departure from traditional approaches to care provision since it offers person-centred support - combing health and social care - to older people in specially-designed, small, homelike environments. Having gained increasing popularity in care homes across developed countries, the impact of this model of service delivery on residents’ quality of life and its c [...]

Background: Purified bacterial collagenase and protease enzymes are commonly used to recover human islets from clinical grade pancreata for subsequent clinical islet transplantation. The high cost of purified enzymes can be prohibitive for recovering human islets from research pancreata used for translational research or pre-clinical studies. In this study, we successfully isolated islets from human research pancreata using enriched collagenase products supplemented with BP Protease (DE Collagenase 800 or Collagena [...]

The present interdisciplinary study discusses the physical foundations of the neurobiological processes occurring during social interaction. The review of the literature establishes the difference between Intentionality and Intention, thereby proposing the theoretical basis of Shared Intentionality in humans. According to the present study, Shared Intentionality in humans (Goal-directed coherence of biological systems), which is the ability among social organisms to instantly select just one stimulus for the entire [...]
