The hyperfine mass splittings of baryons containing a heavy quark are derived at leading order in large N QCD. Hyperfine splittings either preserve or violate heavy quark spin symmetry. Previous work proves that the splittings which preserve heavy quark spin symmetry are proportional to J at order 1/N , where J is the angular momentum of the light degrees of freedom of the baryon. This work pro...

BACKGROUND: COVID-19 increased psychological and physical complaints, including anxiety, depression, pain. OBJECTIVE: We aimed to examine musculoskeletal complaints that may occur in healthcare workers during the pandemic. METHODS: Data were cross-sectional, collected by online questionnaire method consisted of demographic questions, Generalized Anxiety Disorder (GAD-7), Patient Health Question...

Zusammenfassung Hintergrund Die Prävalenzerhebung von Muskel-Skelett-Beschwerden im betrieblichen Kontext basiert oft auf dem Nordischen Fragebogen (NMQ) Kuorinka et al. (1987). Derzeit existiert keine einheitliche deutschsprachige, validierte Übersetzung, zudem weist die Originalversion Unstimmigkeiten auf. Vor Hintergrund, dass entsprechend der Verordnung zur arbeitsmedizinischen Vorsorge (Ar...

the high occurrence of upper extremity musculoskeletal disorders (uemsds) in iranian ironwork industries indicates a need to assess the risk factors of the disorders at such workplaces. in order to prevent such disorders, the occupational repetitive actions (ocra) carried out to obtain an integrated assessment of the various risk factors, classify different jobs and suggest ergonomic designing ...

original article   health, safety and environment management has a vast area in which ergonomics aspects is known as one of the related aspects. in this case study the occupational hygiene by ergonomic intervention was focused. one of the prevalence activities among industrial sectors' worker in the developing countries is manual lifting tasks and other related physical activities which are imp...

Digitalis-like compounds (DLCs), or cardiac glycosides, are produced and sequestered by certain plants and animals as a protective mechanism against herbivores or predators. Currently, the DLCs digoxin and digitoxin are used in the treatment of cardiac congestion and some types of cardiac arrhythmia, despite a very narrow therapeutic index. P-glycoprotein (P-gp; ABCB1) is the only known ATP-dep...

OBJECTIVE This cross-sectional study aimed at analyzing: 1. the main musculoskeletal symptoms (MSS) presented by hospital nursing workers and; 2. personal, occupational, and health factors related to MSS among them. METHOD Two questionnaires were filled in by 245 nurse technicians (NTs) and licensed practical nurses (LPNs) (response rate 95%) associated with direct patient care sectors from a...

BACKGROUND AND OBJECTIVES Assessment of ergonomic strain during robotic surgery indicates there is a need for intervention. However, limited data exist detailing the feasibility and acceptance of ergonomic training (ET) for robotic surgeons. This prospective, observational pilot study evaluates the implementation of an evidence-based ET module. METHODS A two-part survey was conducted. The fir...
