The production of organic acids and changes during decomposition of rice straw amended with tricalcium phosphate (TCP) and Udaipur rock phosphate (URP) were studied under laboratory conditions. The organic C content of rice straw decreased and total N increased with time, resulting in a decrease in C:N ratio as the decomposition progressed. The pH decreased to acidic range in all the treatments on day 15, but became alkaline again later on. Soluble P increased at 15 days after incubation, declined later during decomposition, and was highest in the treatments containing TCP and Aspergillus awamori inoculation. Citric, oxalic, formic and maleic acids were detected during decomposition of rice straw and maximum amounts were present on day 15. Citric and oxalic acids were responsible mainly for P solubilization from TCP and URP; generally, citric acid was the most effective in P solubilization.

Separation of pubic symphysis during delivery is a rare complication resulting in considerable and prolonged morbidity for parturient women. The usual presentation is that of something giving way in the region of the symphysis pubis sometimes with an audible crack at the time of delivery. Unbearable pain on moving from side-to-side and on performing any weight-bearing activity (such as walking or climbing stairs) precludes ambulation in the immediate postpartum period. This could be accompanied by disruption of the sacroiliac joint, hemorrhage, or urine incontinence in severe cases. Radiography, ultrasound, and magnetic resonance imaging are the diagnostic modalities that aid confirmation of diagnosis. The magnitude of separation does not correlate well with the severity of symptoms. Treatment modalities range from conservative management (including analgesics, pelvic binders, transcutaneous nerve stimulation) and chiropractic management to orthopedic interventions such as external fixation or open reduction and internal fixation. Since postpartum pain is frequently dismissed as attributable to labor and childbirth, the diagnosis of pubic symphysis diastasis is often delayed and sometimes missed altogether. Since there is no consensus in the scientific literature on the definition, etiopathogenesis, and management of this rare complication, we attempted to review the literature on the subject and present a series of two cases.

Astaxanthin is a ketocarotenoid, super antioxidant molecule. It has higher antioxidant activity than a range of carotenoids, thus has applications in cosmetics, aquaculture, nutraceuticals, therapeutics, and pharmaceuticals.Naturally, it is derived from Haematococcus pluvialis via a one-stage process or two-stage process. Natural astaxanthin significantly reduces oxidative and free-radical stress as compared to synthetic astaxanthin. The present review summarizes all the aspects of astaxanthin, including its structure, chemistry, bioavailability, and current production technology. Also, this paper gives a detailed mechanism for the potential role of astaxanthin as nutraceuticals for cardiovascular disease prevention, skin protection, antidiabetic and anticancer, cosmetic ingredient, natural food colorant, and feed supplement in poultry and aquaculture. Astaxanthin is one of the high-valued microalgae products of the future. However, due to some risks involved or not having adequate research in terms of long-term consumption, it is still yet to be explored by food industries. Although the cost of naturally derived astaxanthin is high, it accounts for only a 1% share in total astaxanthin available in the global market. Therefore, scientists are looking for ways to cut down the cost of natural astaxanthin to be made available to consumers.

Acne vulgaris (AV) is the familiar chronic skin ailment affecting most of the individuals. This multifarious, disease involves the bacterium gram-positive, anaerobic Propionibacterium acnes (P. acnes) which resides on skin microflora, and participated in acne inflammation and acne lesions. The object of this review is to discuss presently available in vitro, ex vivo, and in vivo models to evaluate the cosmetic formulations that are developed for dealing and prevention of acne formation. These various available models offer new chances for further research on biologically active materials, drugs & pharmaceutical as well as cosmetics for acne treatment.
