Abstract Background The mechanism of iron (Fe) uptake in plants has been extensively characterized, but little is known about how Fe transport to different subcellular compartments affects localization rice seed. Here, we discuss the characterization a vacuolar transporter 2 ( OsVIT2 ) T-DNA insertion line osvit2 and report that knockdown mitochondrial MIT expression seed localization. Findings accumulated less their shoots when grown under normal or excess conditions, while accumulation was...

Cabbage aphid Brevicoryne brassicae (L.) (Hemiptera: Aphididae) is a serious pest of crucifers in Pakistan. After incidences poor control by recommended insecticides, the current study was undertaken to find out status insecticide resistance Pakistani B. brassicae. Apterous adult aphids were bioassayed from 2006 2010 for their response 12 insecticides using an immersion method. No or very low levels found endosulfan; and organophosphates: chlorpyrifos profenofos. Resistance methomyl;...

Poultry meat is the inexpensive sources of protein for humans. acceptability always depends on quality. Cereals, fishmeal, soybean are commonly used Protein major nutrient costing higher value compared to other ingredients. worms can be as source because limited resources. One such insect meal, which has come up an alternative feed poultry. This also improves quality and taste poultry desired by many people. The study involved rearing fresh dried mealworm (Tenebrio molitor) fruit waste their...

Shamimin, a C-flavonol glucoside from Bombax ceiba leaves showed significant potency as hypotensive agent at the doses of 15 mg/kg, 3 1 mg/kg and hypoglycaemic activity 500 in Sprague-Dawley rats. Further studies revealed that it did not cause any mortality mice dose g/kg but rats is lethal dose. Aqueous methanolic extracts one its fractions were also subjected to pharmacological toxicological screening.

Late Cryogenian to Ediacaran magmatism of the East-Eastern Nigerian Terrane (E-ENT) in Pan-African mobile belt provides a critical geological record that is important for unravelling regional tectonic and geodynamic setting. A detailed study utilizes whole-rock elemental, in-situ zircon U-Pb Lu-Hf isotopic geochemistry are conducted on post-collisional granitoids from Hawal Massif E-ENT. These metaluminous slightly peraluminous, alkali-calcic calc-alkalic ferroan composition. ages suggest...

Extensive research has been dedicated to develop compounds that can target multiple aspects of Alzheimer's disease (AD) treatment due a growing understanding AD's complex multifaceted nature and various interconnected pathological pathways. In the present study, series biological assays were performed evaluate potential tryptamine analogues synthesized earlier in our lab as multi-target-directed ligands (MTDLs) for AD. To assess inhibitory effects compounds, vitro employed. Three

Present study was conducted to appraise the inhibitory effects of cadmium applied at different time intervals on various growth and biochemical parameters in two maize lines, Maize-TargetedMutagenesis 1 2 (MTM-1 MTM-2). Twenty-day-old seedlings were exposed 0, 3, 6, 9, 12 mg CdCl kg −1 sand. Both lines exhibited significant perturbations important attributes being employed for screening crops tolerance. The results showed that a higher concentration (12 ) considerably reduced plant line...

Hypotensive effects of aloeemodin, aloin A, elgonica dimer A and bisbenzopyran from Aloe barbadensis have been studied. Aloeemodin has emerged as a potent hypotensive agent in current pharmacological investigations caused 26 %, 52 79 % falls mean arterial blood pressure at the corresponding doses 0.5, 1, 3 mg/kg rats. The paper also describes absolute configuration (1).

In the present study, some 9-aminoacridine derivatives have been synthesized by condensation of with substituted phenacyl, benzoyl, and benzyl halides (RM1-RM6). Compounds were investigated for acetylcholinesterase butyrylcholinesterase inhibition potential, considering these enzymes playing a key role in Alzheimer’s disease. All showed better than standard galantamine, whereas except RM4, all exhibit results tacrine, well-known acridine derivative used treatment

In the present investigation, different strains of Plant growth-promoting rhizobacteria (PGPR), namely Bacillus megaterium, Pseudomonas fluorescens and subtilis were evaluated for their effects on wheat as well soil properties under field conditions at two sites having sandy loam silt type soils. PGPR either singly or in consortia. Amongst all treatments, inoculated with consortia was found most effective it increased grain yield up to 53% over control soil, whereas, corresponding less...

Abstract Pink bollworm, Pectinophora gossypiella (Saunders) (Lepidoptera: Gelechiidae) has become a potential pest of cotton by causing substantial yield losses around the world including Pakistan. As limited past research investigations on dietary aspect P. are available, present study was conducted. A number biological aspects were studied rearing different larval diets that prepared using indigenous elements. The standard/laboratory diet comprised wheat germ-meal 34.5, casein 30.0,...
