The role of light in the fruiting of Panus fragilis was explored under controlled temperature and light cycles. No fruiting occurred in the absence of light. A daily light cycle of 1.5 h at 792 ft-c was sufficient to produce fruiting initials, but not mature sporophores. Only at the longest daily light cycle tested, 12 h at 792 ft-c, were mature sporophores produced. The time required was 22–31 days with a daily fluctuating temperature cycle of 22 °C for 12 h followed by 8 °C for 12 h. The development of a pink pigment associated with fruiting initials and young sporophores was strongest at the longer light cycles and almost absent in the short cycles.

The present study was performed to compare four nonlinear regression models (segmented, beta, beta modified, and dent-like) to describe the emergence rate–temperature relationships of six lentil (Lens culinaris Medik) cultivars at field experiment with a range of sowing dates, with the aim of identifying the cardinal temperatures and physiological days (i.e., number of days under optimum temperatures) required for seedling emergence. Models and statistical indices were calibrated using an iterative optimization method and their performance was compared by root mean square error (RMSD), coefficient of determination (R2) and corrected Akaike information criterion correction (AIC). The beta model was found to be the best model for predicting the response of lentil emergence to temperature, (R2= 0.99; RMSD= 0.005; AICc= -232.97). Based on the model outputs, the base, optimum, and maximum temperatures of seedling emergence were 4.5, 22.9, and 40 °C, respectively. The Six physiological days (equivalent to a thermal time of 94 °C days) were required from sowing to emergence

: Thymoquinone (TQ) is one of the leading phytochemicals, which is abundantly found in Nigella sativa L. seeds. TQ exhibited various biological effects such as antioxidant, anti-inflammatory, antimicrobial, and anti-tumoral in several pre-clinical studies. Parkinson's disease (PD) is a long-term neurodegenerative disease with movement difficulties, and the common feature of neurodegeneration in PD patients is caused by dopaminergic neural damage in the substantia nigra pars compacta. The neuroprotective activity of TQ has been studied in various neurological disorders. TQ-mediated neuroprotection against PD yet to be reported in a single frame; therefore, this review is intended to narrate the potentiality of TQ in the therapy of PD. TQ has been shown to protect against neurotoxins via amelioration of neuroinflammation, oxidative stress, apoptosis, thereby protects neurodegeneration in PD models. TQ could be an emerging therapeutic intervention in PD management, but mechanistic studies have been remained to be investigated to clarify its neuroprotective role.

Nigella sativa (NS), commonly known as black cumin, has been used for medicinal purposes. Traditionally the seeds and its oil are used in several diseases. The greatest part of the remedial properties of this plant is due to the presence of thymoquinone (TQ) which is a major active chemical component of the essential oil. The current study performed to evaluate the effect of Nigella sativa Oil (NSO) extract on the neurotoxic and hepatotoxic potentials from Valproic acid (VPA) administration. Also we summarize recent findings emphasizing the role of main neurotoxic and hepatotoxic markers and oxidative stress in study’s case. Neurotoxicity was induced by VPA at dose of (500 mg/kg b.wt) by gastric intubation daily for 30 day. These rats received NSO extract was given orally at dose of (0.5 ml/kg b.wt) daily for 30 days after VPA administration. The current results revealed that NSO extract treatment ameliorated significantly the elevated levels of the neurotoxic and hepatotoxic biomarkers which elevated as a result to VPA administration. Moreover, NSO extract treatment ameliorated the non-enzymatic antioxidant, brain and liver lipid peroxidation (LPO) and glutathione (GSH) concentration and the enzymatic antioxidant, brain and liver catalase(CAT) activity.
