in study, spherical silver nanoparticles (snps) were synthesized by chemical reduction method from a metal precursor silver nitrate in presence of an anionic surfactant and strong reducing agent. in this experimental work, snps are synthesized in presence of different concentration of stabilizing agent and effect of stabilizing agent on size distribution of snps have been observed. further anti...
Photographic evidence of the Large-toothed Ferret Badger Melogale personata I. Geoffroy Saint-Hilaire (Carnivora: Musteliade) in Annapurna Conservation Area, Nepal
INTRODUCTION To investigate the feasibility and clinical efficacy of using a toothed plate and hollow lag screw in the surgical treatment of posterior cruciate ligament (PCL) avulsion fractures of the tibia. METHODS A total of 21 patients were treated with open reduction and internal fixation using a toothed plate and hollow lag screw, through a posteromedial approach using an inverted L-shap...
Silver nanoparticles are widely used in various sciences and industries. Widespread use of silver nanoparticles has caused entrance of it to the aquatic environment through Wastewater, so it is necessary to investigate the effects of silver nanoparticles on various aquatic organisms. The present study investigated the lethal concentration and bioaccumulation of silver nanoparticles and its comp...

Phytodermatoses are skin lesions secondary to prolonged contact with certain herbs. Many plants have been described responsible for this type of incident. Mrs. H., 50 years old, without pathological history, presented at the consultation for a sharp pain in the face, without any functional sign. The questioning found the application of a poultice, advised by a neighbor, containing the "Artemisi...
Concentrations and patterns of polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) in the blubber of the five most common toothed whales off the Northwest Iberian Peninsula (NWIP), specifically common dolphin, long-finned pilot whale, harbour porpoise, striped dolphin and bottlenose dolphin, were investigated. The study revealed that differences in PCB and PBDE concentra...
Echolocating toothed whales produce high-powered clicks by pneumatic actuation of phonic lips in their nasal complexes. All non-physeteroid toothed whales have two pairs of phonic lips allowing many of these species to produce both whistles and clicks at the same time. That has led to the hypothesis that toothed whales can increase the power outputs and bandwidths of clicks, and enable fast cli...
Developmental genetic studies of evolved differences in morphology have led to the hypothesis that cis-regulatory changes often underlie morphological evolution. However, because most of these studies focus on evolved loss of traits, the genetic architecture and possible association with cis-regulatory changes of gain traits are less understood. Here we show that a derived benthic freshwater st...
Archaic toothed mysticetes represent the evolutionary transition from raptorial to bulk filter feeding in baleen whales. Aetiocetids, in particular, preserve an intermediate morphological stage in which teeth functioned alongside a precursor of baleen, the hallmark of all modern mysticetes. To date, however, aetiocetids are almost exclusively Late Oligocene and coeval with both other toothed my...
