Serum samples from 88 (76 infertility males and 12 control) were collected and assayed by Sandwich-ELISA technique. Infertility patients were distributed to Primary and secondary infertility type with a 66(86.84%) and 10(13.016%) patient, respectively (P?0.01). All infertility patients showed an elevated mean sera levels of TGF-?1 with (0.734±0.45 pg/ml), as compared with the controls (0.670± 0.393 pg/ml). No statistical differences were appeared between the two groups included in the present study regarding this cytokine (P>0.05).

Starting from its outbreak, the disease's understanding has advanced quickly; multi-organ involvement is the key factor affecting the prognosis of the disease. Mortality and morbidity are closely related to acute respiratory distress syndrome, renal failure, cardiac failure, liver damage, multi-organ failure, and shock. In the initial phases of viral infection, detecting and controlling pro-inflammatory responses are essential. Throughout patient monitoring, it's crucial to consider the COVID-19 treatment's unknowable response. It has been discovered that IL-6 is causally linked to greater mortality. It is a reliable indicator regarding the progression of clinical profile as well as the prognosis of the disease. A highly important cytokine, after the activated macrophages, is it.

The yield of total bikaverin in F. oxysporum shake flask culture was improved by optimizing cultivation variables such as complex medium, carbon supply, nitrogen source, temperature, medium pH, and incubation period. The maximum production of complete bikaverin was found after 10 days at 28°C in Potato dextrose broth [PDB] supplemented with 2% glucose, 2% corn step liquor, and a pH of 5.5.

The free energy of the proposed ferrimagnet has been evaluated depending on the trial Hamiltonian operator. Minimizing the free energy, one may induce characteristic features of the longitudinal magnetizations, phase transitions and spin compensation temperatures, in the ranges of low temperatures, respectively. In particular, we study the effect of crystal field domains on the critical phenomena for the proposed model. The sublattice magnetization dependence of freerenergy function has been discussed as well.
