REVIEW
Geeta Karyakarte, Alka Dive, Ashish Bodhade, Shubhangi Khandekar
In today's era of forensic investigations, hard copies of forensic data have been replaced by digital records. However, wide availability of image processing software makes digital image manipulation an easy and low-cost way to distort or conceal facts. This review article aims to understand fraudulence in the digital records in forensic odontology and the various ways to detect as well as prevent it to an appreciable extent. Types of image fraudulence, ways to detect this fraudulence, and measures to prevent it to an appreciable extent have been discussed...

Lucanidae have long received great attention for their adults. However, differentiating between the larvae of stag beetles is difficult and remains unsatisfactorily resolved due to the microscopic features separating groups. In the current study, the larvae of Prismognathus dauricus Motschulsky, 1860 were investigated using light and scanning electron microscopy. The larvae of P. dauricus are atypical for the following characters: i) the epipharynx possesses anteriorly eleven protophoba arranged in a semi-round line; ii) the par stridens consists of 31 ± 0...

Studies on the egg plasma membrane-associated tyrosine kinase Src have shed light on the identity of the molecular machinery that is responsible for gamete interaction and possibly fusion in African clawed frog Xenopus laevis. Here we describe our protocol for identifying and analyzing molecular and cellular machinery that contributes to a variety of biological processes in the course of oogenesis, oocyte maturation, egg fertilization, and early embryogenesis in Xenopus. Our current special interest is to evaluate the hypothesis that the oocyte/egg membrane microdomain (MD)-associated uroplakin III-Src system is responsible for mediating sperm-egg membrane interaction/fusion signal to the oocyte/egg cytoplasm to initiate embryonic and zygotic development in this species...

The authors developed a new surgical technique of retropupillary implantation of an iris-claw intraocular lens (RP-ICIOL). RP-ICIOL is an alternative surgical option to the scleral-fixation technique for the treatment of aphakia without capsular support. Several studies have shown that RP-ICIOL is efficient and safe. However, although it is easier to perform than scleral fixation, it presents some critical issues related to the enclavation procedure. The success of the correct enclavation without excessive surgical manipulations, with subsequent pigment dispersion and without pupil distortion, is highly related to the surgical skills of the individual surgeon...

Dismembered cats ( Felis catus) have been found in North American schoolyards, parks, walkways, or lawns and sometimes result in local media attention. When a member of the public encounters these cats, they commonly report finding either the cranial or caudal half of a cat in a prominent location. Such findings cause public consternation and pose difficulties to investigators in identifying whether animal abuse has occurred and whether to concentrate resources on the investigation. This report describes necropsy results from 53 cats involved in such instances in the cities of Edmonton and St...

The ABC model in flower development represents a milestone of plant developmental studies and is essentially conserved across a wide range of angiosperm species. Despite this overall conservation, individual genes in the ABC model are not necessarily conserved and sometimes plays a species-specific role, depending on the plant. We previously reported that carpels are specified by the YABBY gene DROOPING LEAF (DL) in rice (Oryza sativa), which bears flowers that are distinct from those of eudicots. By contrast, another group reported that carpels are specified by two class C genes, OsMADS3 and OsMADS58...

Sexual differentiation and primary and secondary sexual characteristics in male crustaceans are modulated by hormones produced in the androgenic gland (AG). The AG is also responsible for the determination of morphotypes in caridean shrimps, such as Macrobrachium amazonicum that shows four morphotypes: translucent claw (TC), cinnamon claw (CC), green claw 1 (GC1) and green claw 2 (GC2). Here, we verified the anatomical, histological and ultrastructural characteristics of the AG in different morphotypes of this species with both amphidromous and hololimnetic life cycles...

Functionally characterizing plant membrane transport proteins is challenging. Typically, heterologous systems are used to study them. Immature eggs (oocytes) of the South African clawed frog Xenopus laevis are considered an ideal expression system for such studies. These large oocytes have a low number of endogenous transport systems in their plasma membranes and highly express foreign mRNA; the oocyte plasma membrane is the default destination of integral membrane proteins that lack recognized organellar sorting signals...

Background: Gout frequently affects the foot yet relatively little is known about the effects of gout on foot structure, pain and functional ability. This study aimed to describe the impact of gout in a UK primary care population. Methods: A cross-sectional study was nested within an observational cohort study of adults aged ≥50 years with foot pain. Participants with gout were identified through their primary care medical records and each matched on age (±2 years) and gender to four participants without gout...

Many animals that use acoustic communication synchronize their mate attraction signals: individuals precisely time their calls to overlap those of their neighbors. In contrast, synchrony in the mate attraction displays of species with visual/motion-based signals is rare. It has only been documented in five species of fiddler crabs. In all of them, small groups of males wave their single large claw in close synchrony. Here, I review what we know about synchrony in fiddler crabs, comparing the five species with each other to determine whether similar mechanisms and functions are common to all...

In the present study, the incidence of diseases in cattle in the area of a veterinary practice was analyzed spatially. Furthermore, the relationship between the incidence of diseases and the distance to geographical elements was investigated. For this study, all cattle farms that were customers of the ambulatory clinic of the animal hospital in Zurich (Tierspital Zürich) were exactly localized on a map. From clinical and treatment data program (Oblon Data®) all services and drugs between January 1st 2013 and December 31st 2013 were evaluated and added as attributes to the according farm...

BACKGROUND: Migraine may be described as a headache with moderate to extreme pain that is often accompanied by incapacitating neurological symptoms. It is estimated that 12% of the world population suffers from migraine. Although a number of drugs have been used for treatment of migraine, most of these are not effective for every patient and may have undesirable side-effects. Thus there is an enormous unmet need in current migraine therapy for discovering safer and more effective agents...

Our aim was to compare friction and traction forces between two burying beetle species of the genus Nicrophorus exhibiting different attachment abilities during climbing. Specifically, the interaction of adhesive hairs and claws during attachment with respect to various surface properties was investigated by using a 2 × 3 experimental design. Traction force was measured for two different surface energies (hydrophilic vs hydrophobic) varying in roughness from smooth to micro-rough to rough. Nanotribometric tests on single legs were also performed...

Strategies that can make general materials smart are highly desired for developing artificial shape-morphing systems and devices. However, at present, it still lacks universal technologies that enable designable prototyping of deformable 3D micronanostructures. Inspired by natural automation systems, for instance, tendrils, leaves and flowers deform dynamically under external stimuli by varying internal turgor, we report a dual-3D femtosecond laser processing strategy for fabricating smart and deformable 3D micro-actuators based on general photopolymers...

Full-length mitochondrial cytochrome c oxidase I (COI) sequence information from lobster phyllosoma larvae can be difficult to obtain when DNA is degraded or fragmented. Primers that amplify smaller fragments are also more useful in metabarcoding studies. In this study, we developed and tested a method to design a taxon-specific mini-barcode primer set for marine lobsters. The shortest, most informative portion of the COI gene region was identified in silico, and a DNA barcode gap analysis was performed to assess its reliability as species diagnostic marker...

Fabricio H Santos, Cristina A Rheims
Spiders of the family Philodromidae are free-living active predators, with laterigrade legs, eyes without tubercles, two tarsal claws and claw tufts. Although very common in zoological collections, their systematics is poorly known, especially in the Neotropics, and their specimens are usually identified only at family level. In this paper, the genus Gephyrellula Strand, 1932 is revised and the type species, G. violacea (Mello-Leitão, 1918) is redescribed and illustrated. Gephyrellula paulistana (Soares, 1943) is considered a junior synonym of G...

Polyspermy blocking, to ensure monospermic fertilization, is necessary for normal diploid development in most animals. We have demonstrated here that monospermy in the clawed frog, Xenopus tropicalis, as well as in X. laevis, is ensured by a fast, electrical block to polyspermy on the egg plasma membrane after entry of the first sperm, which is mediated by the positive-going fertilization potential. An intracellular Ca2+ concentration ([Ca2+ ]i ) at the sperm entry site was propagated as a Ca2+ wave over the whole egg cytoplasm...

In all amniotes specialized intermediate filament keratins (IF-keratins), in addition to keratin-associated and corneous proteins form the outermost cornified layer of the epidermis. Only in reptiles and birds (sauropsids) the epidermis of scales, claws, beaks, and feathers, largely comprises small proteins formerly indicated as "beta-keratins" but here identified as corneous beta-proteins (CBPs) to avoid confusion with true keratins. Genes coding for CBPs have evolved within the epidermal differentiation complex (EDC), a locus with no relationship with those of IF-keratins...
