Meiosis is an event of high evolutionary stability that culminates in a reduction of chromosome number. Several abiotic environmental factors such as heat may cause anomalies at genetic level that ultimately impair fertility of the plant. In the present study, the effect of heat stress on various morphological and cytological parameters has been studied in Lathyrus sativus. The most interesting...

Humans possess pathogen-avoidance mechanisms that respond to the visual perception of morphological anomalies in others. We investigated whether obesitymay trigger thesemechanisms. Study 1 revealed that peoplewho are chronically concerned about pathogen transmission havemore negative attitudes toward obese people; this effect was especially pronounced following visual exposure to obese individu...

The aim of this paper is to describe a unique and unusual case of concomitant appearance of morphological dental anomalies in the maxillary anterior region, along with its management in a patient with no systemic abnormality. This case report describes the clinical and radiographic features of talon cusp, dens invaginatus, shovel-shaped incisors and a supernumerary tooth occurring in a single p...

Developmental abnormalities of the cerebral venous system occur due to stopped development of the venous system and continuing primitive embryonal veins draining into an abnormal draining vein. Association with occult vascular malformations was detected in patients with developmental venous anomalies in 40 %; it represents a risk of intracerebral bleeding. Therefore, further monitoring of the p...

Objective: To identify various morphological variations in surface of human liver. Materials and Methods: The study was conducted in 60 adult human liver specimens by dissection method. Results: out of 60 specimens studied 25cases (41%) showed variations. Presence of additional lobe in 3 cases (5%); accessory fissures in 8 cases (13%); short gall bladder in 3 cases (5%); elongated left lobe in ...

We report on an isolated chest-wall asymmetry with imaging findings of multiple vertebral and related rib defects in an Ivorian male newborn. He was born of a healthy and young couple without parental lineage, neither family malformative history nor teratogen exposure. This clinical presentation advocates Jarcho-Levin syndrome, a rare sporadic or familial disorder inherited as autosomal dominan...

Left ventricular endocardial fibroelastosis was diagnosed by echocardiographic scanning in a fetus at 20 weeks' gestation. Repeated prenatal examination over the next 20 weeks' gestation showed the development of the left ventricle from a chamber with a dilated cavity to a small cavity with a very thick wall. These findings were confirmed at necropsy and by the absence of other morphological an...

The otherwise considered being one of the smallest and weakest teeth in the arch, mandibular second premolars have been found to almost double its size in macrodontia. Such anomalies of morphological alterations have caused the teeth to be more weak and prone to diseases, as accredited to the increased surface area and particular morphology. Bilateral mandibular second premolar macrodontia is a...

Megalencephaly-capillary malformation-polymicrogyria syndrome (MCAP), previously known as macrocephaly-cutis marmorata telangiectatica congenita and macrocephaly-capillary malformation syndrome, is a rare multiple-malformation syndrome that is characterized by progressive megalencephaly, capillary malformations of the midline face and body, or distal limb anomalies such as syndactyly. Herein, w...

A quantitative morphological assessment was carried out of the cellularity and staining properties of the cells of the layers of the human cerebellar cortex, both in the normal child and in 41 children suffering from a series of disorders including mental retardation. A computerized image analyser and highly standardized procedures were used. All of the cases of mental retardation and some case...
