Abstract:

Magnospina gen. n. was created to relocate species of the dentifera-group from Alona sensu lato (Crustacea: Cladocera) and include Magnospina dentifera comb. n. and Magnospina siamensis comb. n. The synapomorphies of the Magnospina gen. n. are (1) basal spines longer than 2/3 of the postabdominal claw, (2) presence of 1–4 large denticles, broad at their bases, protruding downwards, without setules between them. Morphological traits such as habitus, rostrum and postabdomen shape, armature of IDL setae, number of setae on the exopod of limb III are also important in the distinction between Magno

Abstract:

We compare several populations of the glass-perchlet Parambassis siamensis (Fowler 1937) (Teleostei: Ambassidae) sampled throughout Peninsular Malaysia to determine their degree of differentiation, using both morphological and molecular characters. Our morphological analyses do not show evidence for the presence of more than one species, with the range of morphometric and meristic characters overlapping among populations. Our genetic analysis using partial sequences of the mitochondrial gene coding for the protein cytochrome c oxidase I (COI) reveals the existence of two clades that diverge fr

Abstract:

The venom of the Russell’s viper (Daboia siamensis) contains neurotoxic and myotoxic phospholipase A2 toxins which can cause irreversible damage to motor nerve terminals. Due to the time delay between envenoming and antivenom administration, antivenoms may have limited efficacy against some of these venom components. Hence, there is a need for adjunct treatments to circumvent these limitations. In this study, we examined the efficacy of Chinese D. siamensis antivenom alone, and in combination with a PLA2 inhibitor, Varespladib, in reversing the in vitro neuromuscular blockade in the chick bive

Abstract:

Analysis of an acetone/hexane (1:1) extract of the seeds of Chisocheton siamensis led to the isolation of a novel limonoid, chisosiamensin (1), along with five known limonoids, dysobinin (2), azadiradione (3), mohinin (4), epoxyazadiradione (5), and 6α-acetoxyepoxyazadiradione (6). Their structures were characterized by spectroscopic methods, including UV, IR, NMR, and MS. All isolated limonoids were reported for the first time as secondary metabolites of C. siamensis.Key words: Chisocheton siamensis, Meliaceae, chisosiamensin, limonoids.

Abstract:

The heterogeneity in venom composition and potency in disparate Eastern Russell’s viper (Daboia siamensis) populations has repercussions for the efficacy of antivenoms. This is particularly pronounced in geographical areas in which the venom of the local species has not been well studied and locally produced antivenoms are unavailable. In such cases, alternative therapies following envenoming, which are not limited by species specificity, may be employed to complement antivenoms.

A comparative study was done with the reference bacterium Cupriavidus necator. Fourteen bacterial strains were isolated from Polluted Landfills and Effluent Treatment Plant. Four bacterial isolates having the ability to produce PHA were selected. Orange peel and Onion peel were substituted for carbon source

The use of plant growth-promoting rhizobacteria (PGPR) for the bioremediation of heavy metal cadmium (Cd) and for enhancing plant growth in Cd-polluted soil is widely recognized as an effective approach. This study aimed to isolate Cd-resistant bacteria with plant growth-promoting (PGP) traits from the rhizosphere of vegetables subjected to metal contamination and to investigate the mechanisms associated with Cd adsorption as well as its impact on Cd uptake in lettuce. Six Cd-resistant bacterial strains were isolated from rhizosphere soil, among which the R27 strain exhibited the highest toler

Colletotrichum spp. is a major group of plant pathogens responsible for anthracnose on a range of economically important hosts. Its occurrence on OLA remains unresolved. To investigate the diversity, morphology, phylogeny, and biology of Colletotrichum spp., 32 fungal isolates were obtained from 30 OLA-affected leaves collected from five different farms, in t
