Strategies for senolytic drug discovery.

Senolytics are a category of drugs that reduce the impact of cellular senescence, an effect associated with a range of chronic and age-related diseases. Since the discovery of the first senolytics in 2015, the number of known senolytic agents has grown dramatically. This review discusses the broad categories of known senolytics-kinase inhibitors, Bcl-2 family protein inhibitors, naturally occurring polyphenols, heat shock protein inhibitors, BET family protein inhibitors, P53 stabilizers, repurposed anti-cancer drugs, cardiac steroids, PPAR-alpha agonists, and antibiotics.

The positives, the challenges and the impact; an exploration of early career nurses experiences in the Emergency Department.

Background: The intense working environment of the Emergency Department (ED) is exciting and rewarding; but is renowned for high staff turnover and burnout. The wellbeing and retention of the existing workforce is imperative. The purpose of this study was to explore the experiences of early careers nurses in the ED; identify aspects of ED they enjoyed, the challenges and explore potential coping mechanisms used to mitigate negative situations.

Identifying HSV-1 Inhibitors from Natural Compounds via Virtual Screening Targeting Surface Glycoprotein D.

Herpes simplex virus (HSV) infections are a worldwide health problem in need of new effective treatments. Of particular interest is the identification of antiviral agents that act via different mechanisms compared to current drugs, as these could interact synergistically with first-line antiherpetic agents to accelerate the resolution of HSV-1-associated lesions. For this study, we applied a structure-based molecular docking approach targeting the nectin-1 and herpesvirus entry mediator (HVEM) binding interfaces of the viral glycoprotein D (gD).

Virtual screening and in vitro validation of natural compound inhibitors against SARS-CoV-2 spike protein.

The COVID-19 pandemic caused by the SARS-CoV-2 virus has led to a major public health burden and has resulted in millions of deaths worldwide. As effective treatments are limited, there is a significant requirement for high-throughput, low resource methods for the discovery of novel antivirals. The SARS-CoV-2 spike protein plays a key role in viral entry and has been identified as a therapeutic target.

Predatory Publishing: How to Safely Navigate the Waters of Open Access.

Open access publishing enables scholarship to be openly accessible to everyone, which has countless benefits. However, the open access movement has opened the door for "predatory publishers" to take advantage of researchers surviving in this publish or perish academic landscape. Predatory journals are becoming increasingly common.

Abnormal sebaceous gland differentiation in 10 kittens ('sebaceous gland dysplasia') associated with generalized hypotrichosis and scaling.

A rare congenital dermatosis, characterized by progressive hypotrichosis with variable scaling and crusting, occurred in 10 short-haired kittens in North America and Europe. Lesions appeared at between 4 and 12 weeks of age, commencing on the head and becoming generalized. The tail was spared in two kittens.

Neonatal brachial plexus injury: comparison of incidence and antecedents between 2 decades.

Objective: We sought to compare the incidence and antecedents of neonatal brachial plexus injury (BPI) in 2 different 5-year epochs a decade apart following the introduction of specific staff training in the management of shoulder dystocia.

Study Design: All infants with BPI were prospectively identified during 2004 through 2008. Injuries were correlated with maternal details and intrapartum events and compared with the earlier series.

Treatment of feline herpesvirus-1 associated disease in cats with famciclovir and related drugs.

Background: Feline herpesvirus 1 (FHV-1) is a common cause of ocular and upper respiratory disease in cats and kittens, and a potential cause of eosinophilic dermatitis.

Hypothesis: The systemic anti-herpes drug, famciclovir (Famvir; Novartis), would be effective in the clinical management of disease attributable to FHV-1, including conjunctivitis, keratitis, corneal sequestra, rhinosinusitis and FHV-1 associated dermatitis.

Clinical Outcome: Oral famciclovir was used to treat signs considered referable to FHV-1 in 10 cats: four had primary ocular disease, two had rhinosinusitis and four had FHV-1 associated dermatitis.

Adverse effects of ketoconazole in dogs--a retrospective study.

Although ketoconazole has been used extensively in dogs for the treatment of various fungal infections, information about adverse effects is mainly anecdotal. Common adverse effects in humans include dose-dependant anorexia, nausea and vomiting, allergic rashes and pruritus. Drug-induced hepatitis is very rare, but potentially fatal.

Pemphigus foliaceus in 91 dogs.

A retrospective study of 91 dogs with pemphigus foliaceus was performed. Clinical signs of the disease included crusts (n=79), pustules (n=36), and alopecia (n=33). Lesions were most common on the trunk (n=53), inner pinnae (n=46), face (n=37), and foot pads (n=32).

CCNU in the treatment of canine epitheliotropic lymphoma.

This retrospective study examined the use of CCNU (1-[2-chloroethyl]3-cyclohexyl-1-nitrosurea) in 36 dogs with epitheliotropic lymphoma. Thirty-one (86%) dogs had the cutaneous form of disease, and 5 (14%) dogs had the oral form of disease. Nineteen (51%) dogs were treated with other chemotherapeutic agents before receiving CCNU.

Long-term use of cyclosporine in the treatment of canine atopic dermatitis.

This retrospective study of 51 dogs with atopic dermatitis (AD) treated with cyclosporine (CsA) for a minimum of 6 months assessed the frequency of dosing and the need for continual treatment to control clinical signs. The study evaluated both medical records and information supplied by the owners in the form of written questionnaires and telephone follow-up. Laboratory parameters, possible adverse effects and owner satisfaction were assessed.
