Black Seeds (Nigella sativa) Medical Application and Pharmaceutical Perspectives.

Among the various medicinal plants, the black seed is emerging as a miracle herb with a rich historical background, as much research has revealed its wide spectrum of pharmacological potential. In this collection of literature, we have encountered and presented the preclinical treatment, as alternative medicine of Nigella sativa in the prevention and treatment of various diseases, as well as those that continue to be discovered by contemporary actual scientific data. Research to date has confirmed the pharmacological potential of the seed of Nigella sativa, its oil and extracts of some of its bioactive constituents, which possess remarkable pharmacological activity, in vitro and in vivo against a large spectrum of diseases, and it has been found that the use of black seed is relatively safe. Black Seed has been extensively studied for its biological activity and therapeutic potential and has been found to possess a broad spectrum of activities. Clinical trial investigations into the therapeutic effects of Nigella sativa affect the hypoglycemic, hypolipidemic, and bronchodilator effects and have passed clinical trials and received the green light to allow the next stage of clinical trials toward therapeutic drug design. However, there is still room and multidimensional research needed for prospective clinical trials in certain groups of animals before they can be applied to humans as pharmaceutical therapies.

Local colonisations and extinctions of European birds are poorly explained by changes in climate suitability.

Climate change has been associated with both latitudinal and elevational shifts in species' ranges. The extent, however, to which climate change has driven recent range shifts alongside other putative drivers remains uncertain. Here, we use the changing distributions of 378 European breeding bird species over 30 years to explore the putative drivers of recent range dynamics, considering the effects of climate, land cover, other environmental variables, and species' traits on the probability of local colonisation and extinction. On average, species shifted their ranges by 2.4 km/year. These shifts, however, were significantly different from expectations due to changing climate and land cover. We found that local colonisation and extinction events were influenced primarily by initial climate conditions and by species' range traits. By contrast, changes in climate suitability over the period were less important. This highlights the limitations of using only climate and land cover when projecting future changes in species' ranges and emphasises the need for integrative, multi-predictor approaches for more robust forecasting.

Ecological barriers mediate spatiotemporal shifts of bird communities at a continental scale.

Species' range shifts and local extinctions caused by climate change lead to community composition changes. At large spatial scales, ecological barriers, such as biome boundaries, coastlines, and elevation, can influence a community's ability to shift in response to climate change. Yet, ecological barriers are rarely considered in climate change studies, potentially hindering predictions of biodiversity shifts. We used data from two consecutive European breeding bird atlases to calculate the geographic distance and direction between communities in the 1980s and their compositional best match in the 2010s and modeled their response to barriers. The ecological barriers affected both the distance and direction of bird community composition shifts, with coastlines and elevation having the strongest influence. Our results underscore the relevance of combining ecological barriers and community shift projections for identifying the forces hindering community adjustments under global change. Notably, due to (macro)ecological barriers, communities are not able to track their climatic niches, which may lead to drastic changes, and potential losses, in community compositions in the future.

A rare case report - Ovary attached to testicle inside hernia sac.

We report the case of a 67-year-old man, father of 3 children with left indirect inguinal hernia containing uterus with cervix, fallopian tube and an ovary attached to the testicle, also spread ovarian tissue and right congenital cryptorchidism. Coincidentally detected during an operation for left inguinal hernia. Persistent Mullerian duct syndrome is a rare form of male pseudo-hermaphroditism detected coincidently during surgical operation on cryptorchidism or inguinal hernia.
