Genetska raznolikost pakistanskih jednogrbih deva slabo je dokumentirana. Ova studija procijenila je genetske varijacije dviju dobro poznatih pasmina pakistanskih deva - mareecha i barela - koje su ...vrlo dobro prilagođene klimi pustinje Cholistan. Deva može poslužiti kao koristan sudionik u lancu opskrbe hranom, osiguravajući mlijeko, meso i druge prehrambene proizvode za život pastira. Da bi se istražio novi svijet resursa, potrebno je više pozornosti za obavljanje standardnih postupaka za genetsku karakterizaciju, razvrstavanje i identifikaciju pasmina deva u zemlji. U tu svrhu, ukupno 66 životinja koje nisu u srodstvu pasmine mareecha (n=35) i barela (n=31) genotipizirane su uporabom 12 označenih mikrosatelitskih lokusa. Veličine fragmenata DNK određene su u ABI 3130 genetskom analizatoru. Svi mikrosatelitski markeri uspješno su pojačani i pokazali su polimorfnu narav s prosječnim sadržajem polimorfnih informacija (PIC) od 0,72 i 0,70 za mareecha, odnosno barela pasminu. Ukupno 107 alela s prosječno 8,91 alelom po lokusu u obje pasmine identificirano je tim markerima. CMS15 bio je vrlo polimorfan s 13 alela dok je VOLP-032 bio najniži s 2 lokusa. Fit i Fis vrijednosti bile su niske, ali je uočena velika diferencijacija populacije (17 %) za obje pasmine koje su posljedica migracije pastira u različite udaljene krajeve tijekom promjena klime.
Plant growth regulators and Rhizobium are actively involved in the regulation of flowering, pod formation, nodulation, and ultimately the growth and yield of legumes. However, very limited ...information is available on the combined effect of gibberellic acid (GA3) and Rhizobium on growth attributes and yield of legume crops. This experiment was designed to fill this gap by studying the performance of chickpea under exogenous application of GA3 (10−4 and 10−5 M) alone and in combination with Rhizobium. Exogenous application of GA3 (10−5 M) combined with rhizobium inoculation gave the highest values for number of nodules per plant (16) and their dry biomass (0.22 g). Moreover, GA3 application and seed inoculation with Rhizobium, when applied singly, significantly enhanced chickpea growth. However, the most promising results were obtained by the inoculation of Rhizobium accompanied with GA3 (10−5 M). Plant height, grain and stover yield, and chlorophyll contents were enhanced up to 35%, 39%, 21%, and 51%, respectively. Likewise, the bioaccumulation of macronutrients (N, P and K) was maximum in plants receiving both Rhizobium inoculation and GA3 application. It is concluded that the combined application of Rhizobium and GA3 has synergistic effects on the growth, yield, and nutrient contents of chickpea.
•Integration of PGPR with press mud mitigated heavy metals-induced adverse impacts on aloe vera.•PGPR changed the oxidation state of metals, which subsequently immobilized due to the action of press ...mud.•PGPR and press mud reduced heavy metals uptake in aloe vera plants, achieving successful phyto-stabilization.
Soil pollution due to heavy metal (HM) contamination has emerged as a global issue worldwide owing to their adverse impacts on plant growth. Bioremediation approaches employing living organisms for HM alleviation have gained considerable attention among scientific community. Biological agents such as plant growth-promoting rhizobacteria (PGPR) offer a sustainable way to restore soil health, and their combination with different organic amendments such as press mud (PM) can serve as potential approach for immobilizing HMs in soil. We performed a pot experiment to evaluate the role of individual and combined application of press mud and PGPR strain ‘FQ6’ (identified as Pseudomonas fluorescens) in the phytoremediation of different HMs (Pb, Ni and Cd) and growth promotion of aloe vera. Combined application of FQ6 strain and PM yielded more significant outcomes in terms of all the growth and yield attributes such as leaf length (123 %), plant height (57 %), number of leaves (115 %), fresh and dry weights of gel (246 and 280 %), gel contents (96 %), root length (164 %), root diameter (220 %), no. of root tips (138 %) and root area (315 %), as compared to control. Combined application of FQ6 and PM also led to a significant improvement in different antioxidant activities i.e., CAT (129 %), SOD (48 %), APX (17 %) and POD (83 %) as compared to control. Contrastingly, mobility of these HMs was reduced under combined application of Pseudomonas strain ‘FQ6’ and PM, as there existed a considerable difference between HMs concentrations in soil and plant body. We concluded that joint application of HM-tolerant Pseudomonas FQ6 strain and PM could be an ideal option to alleviate the HM induced adverse impacts on aloe vera by immobilizing them in soil, and subsequently, improving plant growth.
Abstract
Background
Acute pancreatitis is a common, yet complex, emergency surgical presentation. Multiple guidelines exist and management can vary significantly. The aim of this first UK, ...multicentre, prospective cohort study was to assess the variation in management of acute pancreatitis to guide resource planning and optimize treatment.
Methods
All patients aged greater than or equal to 18 years presenting with acute pancreatitis, as per the Atlanta criteria, from March to April 2021 were eligible for inclusion and followed up for 30 days. Anonymized data were uploaded to a secure electronic database in line with local governance approvals.
Results
A total of 113 hospitals contributed data on 2580 patients, with an equal sex distribution and a mean age of 57 years. The aetiology was gallstones in 50.6 per cent, with idiopathic the next most common (22.4 per cent). In addition to the 7.6 per cent with a diagnosis of chronic pancreatitis, 20.1 per cent of patients had a previous episode of acute pancreatitis. One in 20 patients were classed as having severe pancreatitis, as per the Atlanta criteria. The overall mortality rate was 2.3 per cent at 30 days, but rose to one in three in the severe group. Predictors of death included male sex, increased age, and frailty; previous acute pancreatitis and gallstones as aetiologies were protective. Smoking status and body mass index did not affect death.
Conclusion
Most patients presenting with acute pancreatitis have a mild, self-limiting disease. Rates of patients with idiopathic pancreatitis are high. Recurrent attacks of pancreatitis are common, but are likely to have reduced risk of death on subsequent admissions.
