Neriene nigripectoris (Oi, 1960) (Araneae, Linyphiidae) is redescribed and illustrated. Based on the genital conformation, we propose that N. nigripectoris be transferred to the genus Ketambea Millidge & Russell-Smith, 1992. Notes are given on distinguishing Neriene from Ketambea.

A series of 1-(4-(2-allylphenoxy)butyl)piperidin-1-ium halides (4a-d) was synthesized and characterized via spectroscopic methods (FTIR, 1H NMR). The corrosion inhibition of the synthesized halides on carbon steel in water-salt-hydrocarbon environment, saturated with H2S, was investigated. For this purpose, a series of techniques such as gravimetric measurement, potentiodynamic polarisation, and scanning electron microscope (SEM) were used and some thermodynamic parameters of corrosion process (∆Gads., ∆H0 ads., ∆S0ads.) were evaluated.

In a cytotoxicity screen in serum-free medium, Guttiferone F showed strong growth inhibitory effect against prostate cancer cells. Methods: Prostate cancer cells LNCaP and PC3 were treated with Guttiferone F in serum depleted medium. Sub-G1 phase distributions were estimated with flow cytometry. Mitochondrial disruption was observed under confocal microscope using Mitotracker Red staining.

A wide range of phytochemicals are present in apple (Malus domestica Borkh), their production was accelerated when apple was subjected to biotic stress. These chemicals were measured in the leaf of apple cultivar Shireen, healthy and infected by Venturia inaequalis and examined by microscope. Scab-induced metabolic re-programming was analyzed by methanol leaf extract by using Gas Chromatography-Mass Spectrometry, while the mass spectra of the compounds found in the extract were matched with the National Institute of Standards and Technology (NIST) library.

Mycorrhiza is important fungi for agriculture. To study of that plant’s root and soil samples were collected from the different regions of junagadh and near to junagadh district. AMF spores were isolated by Wet-sieving-decanting method and AdhesionFlotation Technique. Morphological studies followed by tryphan blue staining revealed different stages with different components of AM fungi in compound microscope.

The phenotypic changes in target cell induced by an exogenous agent, e.g. biologically active chemical, can be detected by labelling selected organelles with fluorescent dyes and observed under the high-throughput microscope. The changes of known biological targets (e.g. nucleus, proteins, mitochondria, microtubules, etc.) induced by a compound of interest allow predicting its mechanisms of action. High-throughput microscopy with capability of multiparametric imaging in combination with automated image-analysis is referred to as highcontent analysis or high-content screening (HCS).

THE TERM CELL IS DERIVED from the Latin cella, meaning storeroom or chamber. It was first used in biology in 1665 by the English botanist Robert Hooke to describe the individual units of the honeycomb-like structure he observed in cork under a compound microscope. The “cells” Hooke observed were actually the empty lumens of dead cells surrounded by cell walls, but the term is an apt one because cells are the basic building blocks that define plant structure.
