The Impact of COVID-19 on the Mental Well-Being of College Students.

The COVID-19 pandemic has caused an overall increase in stress and depression in society. The aim of the present research was to evaluate the psychological condition of college students during the COVID-19 pandemic and explore factors influencing their daily functioning. The study focused on four main aspects such as mental well-being, sexuality, concern about financial status, and trust in medical authorities.

Assessment of extent of apoptosis and DNA defragmentation in chilled semen of stallions during the breeding season.

The objective of the study was to assess apoptosis and DNA defragmentation in equine semen diluted and chilled to +4°C. Semen was collected from nine fertile stallions, including four Arabian thoroughbreds and five coldbloods. Examinations were carried out immediately after semen collection (0) and at five storage times (24, 48, 72, 96 and 120 h).

Serum levels of acute phase proteins: SAA, Hp and progesterone (P4) in mares with early embryonic death.

The study involved 46 healthy purebred Arabian mares exhibiting regular oestrous cycles that underwent artificial insemination (AI). Pregnancy was detected ultrasonographically (US) in 40 mares. In 15 mares in foal, early embryonic death (EED) was observed during the pregnancy days 14-21.

Batting last as a home advantage factor in men's NCAA tournament baseball.

In baseball and softball, there is a rule that allows the home team to have the last at-bat and thus the final opportunity to win the game. However, in tournament play, this rule is often set aside and, instead, batting order is decided by other means (e.g.

Process and product monitoring of recombinant DNA-derived biopharmaceuticals with high-performance capillary electrophoresis.

High-performance capillary electrophoresis (HPCE) has emerged over the past 20 years as a powerful multidimensional separation tool that is orthogonal to HPLC and comparable to sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) slab gel methods. HPCE is most frequently applied in the QC release testing of recombinant DNA-derived protein and monoclonal antibody (MAb) biopharmaceuticals. HPCE is a rugged and robust separation tool that can be used like HPLC to monitor the purification process, as well as to analyze bulk drug and drug substances.

Sympathetic ophthalmia: induced by vitrectomy not by trauma.

A case of sympathetic ophthalmia that occurred after corneoscleral laceration due to blunt trauma and after vitrectomy was encountered, and the patient was treated without enucleation of the exciting eye; this is the sixteenth case of sympathetic ophthalmia reported to occur after vitrectomy. In the reported cases including the present one, the intervals between the primary trauma or primary intraocular surgery and secondary vitrectomy and the onset of sympathetic ophthalmia were compared with those in patients who suffered from this disease without vitrectomy. The statistical analysis by the probit method revealed that the onset of sympathetic ophthalmia was critically influenced by the secondarily delivered operation, ie, vitrectomy (P less than 0.

[Distribution, absorption and excretion of 198Au-colloid and Na251CrO4 in the chicken (author's transl)].

In order to clarify the suitability of 198Au-colloid and Na251CrO4 as a marker of transit of the gastrointestinal content of the chicken, the distribution, absorption and excretion of 198Au-colloid and Na251CrO4 in the chicken were examined. Orally administered 198Au-colloid was not absorbed by the gastrointestinal tract and excreted into feces. Intravenously injected 198Au-colloid was not excreted into the gastrointestinal tract through the gastrointestinal wall.
