Organic amendments and conservation tillage improve cotton productivity and soil health indices under arid climate.

Long-term different tillage system field trials can provide vital knowledge about sustainable changes in soil health indices and crop productivity. This study examined cotton productivity and soil health indices under different tillage systems and organic materials. The present study was carried out at MNS University of Agriculture, Multan to explore the effect of different tillage systems: conventional tillage (T1), conservation tillage (T2), and organic materials: control (recommended dose of synthetic fertilizers; 160:90:60 kg ha-1NPK), poultry manure (10 t ha-1 PM), compost (10 t ha-1 CM), farmyard manure (20 t ha-1 FYM), and biochar (7 t ha-1 BC) on cotton productivity and soil health indices. Two years field trials showed that different tillage systems and organic materials significantly improved the growth, morphological, and yield attributes of cotton and soil health indices. The cotton showed highest seed cotton yield (3692-3736 kg ha-1), and soil organic matter (0.809-0.815%), soil available nitrogen (74.3-74.6 mg kg-1), phosphorus (7.29-7.43 mg kg-1), and potassium (213-216 mg kg-1) under T2 in comparison to T1 system during both years of field experiment, respectively. Similarly, PM (10 t ha-1) showed highest seed cotton yield (3888-3933 kg ha-1), and soil organic matter (0.794-0.797%), nitrogen (74.7-75.0 mg kg-1), phosphorus (7.39-7.55 mg kg-1), and potassium (221-223 mg kg-1) when these are compared to FYM (20 t ha-1), CM (10 t ha-1), and BC (7 t ha-1) during both years of field experiment, respectively. These findings indicate that conservation tillage system with application of 10 t ha-1 PM are the best practices for the sustainable cotton production and to ensure improvement in the soil health indices under arid climatic conditions.

Stromal vascular fraction-enriched platelet-rich plasma therapy reverses the effects of androgenetic alopecia.

BACKGROUND: Since antiquity, humans have been trying to devise remedies to cure androgenetic alopecia (AGA). These efforts include use of oral and topical concoctions and hair transplant strategies. As AGA affects people of all colors and creed, there has been a continuous effort to find a magic bullet against AGA. Unfortunately, to date, all the strategies to negate AGA effects have limitations and thus require new treatment options. AIM: To evaluate the efficacy of use of stromal vascular fraction (SVF) in androgenetic alopecia patients. METHODS: Stromal vascular fraction was obtained by enzymatic digestion of autologous adipose tissue. The patients were divided into two groups, that is, platelet-rich plasma (PRP) group and SVF-PRP group. In PRP group, only PRP was injected, while in SVF-PRP group a mixture of PRP and SVF was injected in affected scalp areas. After two sessions (4 weeks apart), the patients in both groups were assessed and analyzed using various parameters. RESULTS: Mean hair density in PRP group was increased from 52.44 hair/cm2 to 63.72 hair/cm2 (21.51% increase); while in SVF-PRP group, it was 37.66 hair/cm2 before treatment and 57.11 hair/cm2 after SVF-PRP therapy (51.64% increase). Percentage reduction in pull test was more significant in SVF-PRP group (80.78 ± 5.84) as compared to PRP group (34.01 ± 22.44). The physician and patient assessment scores also indicated a significant improvement in SVF-PRP group. CONCLUSION: A combined SVF-PRP therapy reversed effects of AGA more efficiently as compared to PRP therapy alone.

Efficacy of platelet-rich plasma in androgenetic alopecia patients.

BACKGROUND: Androgenetic alopecia (AGA), a patterned hair loss in both males and females, is a commonly occurring disease worldwide. Conventionally, no curative or satisfactory treatment is available for this condition. Therefore, in the current study, we aim to use platelet-rich plasma (PRP) as an alternative treatment option for the AGA patients. MATERIALS AND METHODS: A total of 30 patients (20 men and 10 women) with AGA were included in the study between February 2017 and November 2017. Blood (9 cc) from each AGA patient was collected in 10 cc syringe, and PRP was isolated using commercially available kit under sterilized conditions. Isolated PRP was injected in the bald areas of scalp of AGA patients. The whole procedure was repeated after one month (two treatment sessions), and patients were followed for six months. The efficacy of PRP for restoration of hair was assessed using parameters such as hair density, terminal to vellus hair ratio, photographs, pull test, physician global assessment score, and patient global assessment score. RESULTS: Mean hair density on first visit (before treatment) was 34.18 ± 14.36/cm2 which was increased to 50.20 ± 15.91/cm2 after 6 months of first treatment (P value <0.05). On a scale of three, mean scores of physician and patient global assessments were 1.45 ± 0.57 and 1.60 ± 0.62, respectively. Mean percentage reduction of hair pulled was 29.2% (P value <0.05) after PRP treatment. Terminal to vellus hair ratio was increased in 60% of patients after PRP therapy. No remarkable adverse effects were noted in patients. CONCLUSION: Results showed that PRP is an effective treatment option in androgenetic alopecia as indicated by higher hair density, satisfactory physician and patient global assessment scores, and increase in terminal to vellus hair ratio.

Pharmacological studies of Adhatoda vasica and Calotropis procera as resource of bio-active compounds for various diseases.

Adhatoda vasica and Calotropis procera species were investigated as a resource for new diverse pharmacological agents including B complex, individual total phenolic compounds and antioxidants for curing and treatments of many infectious diseases in human through advanced analytical methods. These plants are abundant in Khyber Pukhtoon Khawa, Pakistan as well as in all over the world and famous for their unique medicinal importance. These herbaceous species are so far used for animals curing while current exploration of these species showed that these species are a precious resource of various compounds which can be employed in the formation of different drugs. The results showed that the leaf and flower extracts of Adhatoda vasica and leaf extract of Calotropis procera contained higher contents of bioactive compounds. The chemical analysis of the samples resulted in higher values of total phenolic compounds (71.32mg GAE/g), total antioxidants (651% DPPH inhibition), the enzyme catalase (4716µg/g), ash content (16.72%) and pH values in the Calotropis procera, whereas the total carotenoids (1987mg/100g), the enzymes, superoxide dismutase (4566µg/g) and peroxidase (1322µg/g) were higher in leaves of Adhatoda vasica. The flower extract of the Adhatoda vasica was rich in the flavonoids (0.87mg/100g) and organic matter (89.99%) as compared to Calotropis procera. The obtained data for each parameter was interpreted by applying Complete Randomized Design (CRD) along with factorial arrangements. The mean comparison was performed using LSD test at 5% probability level. The presence of these phytochemicals may lead to the conclusion that these herbal plants have the potential for formation of new drugs and can be used as herbal medicine for treatment of different cancer and viral diseases. These compounds are also useful in the treatment of the tumor.
