In the treatment of photoaged skin, glycolic acid works by removing superficial portions of the epidermis and stimulating dermis regeneration. Vitamins A, C, and E should stimulate collagen production and antioxidants should prevent free radical damage and skin aging. However, the effectiveness of different therapies has often relied on subjective methods of assessment. Histologic analysis has seldom been used because of the drawback of permanent scarring. In the literature, the use of a quantitative method for the assessment of facial rejuvenation has been described: the silicone replica technique. The authors' aim was to promote and recommend the use of this technique and, in particular, to test the effect of glycolic acid and multivitamin- and antioxidant-based products on skin texture. The authors performed a prospective, randomized, double-blind, controlled study on 30 women treated topically in the outer canthal region (crow's-feet area). Patients were divided into thr...

Humans’ conscious awareness of objects in their visual periphery is limited. This limit is not entirely the result of reduced visual acuity. Rather, it is primarily caused by crowding—the difficulty identifying an object when it is surrounded by clutter. The effect of crowding on visual awareness in infants has yet to be explored. Do infants, for example, have a fine-grained “spotlight,” as adults do, or do infants have a diffuse “lantern” that sets limits on what they can register in their visual periphery? We designed an eye-tracking paradigm to psychophysically measure crowding in infants between 6 months and 15 months of age. We showed infants pairs of faces at three eccentricities, in the presence or absence of flankers, and recorded infants’ first saccade from central fixation to either face. Infants could discriminate faces in the periphery, and flankers impaired this ability. We found that the effective spatial resolution of infants’ visual perception increased with age, but...

We investigated the relation between appearance-based impressions of hon-esty and individuals' willingness to engage in deceptive behaviors. The data reveal that people who were thought to look dishonest were more likely to volunteer to participate in research that was ...

Solar lentigines are common acquired pigmented lesions on sun-exposed skin. Their histopathological features have been reported as large numbers of melanocytes at the base of clubbed and budding rete ridges. In this study, biopsies were taken from facial solar lentigines in 40 Japanese women, and the sections were stained using hematoxylin-eosin, Fontana-Masson, and immunostained for melanocytes and Langerhans cells in order to verify the histological patterns of Japanese patients. We characterized the histopathological features of solar lentigines on the face and identified two patterns: one pattern (20/40 cases) demonstrated a flattened epidermis with basal melanosis, and the other pattern (20/40 cases) showed epidermal hyperplasia with elongated rete ridges composed of deeply pigmented basaloid cells. We termed the former pattern the "flattened epidermis" group, and the latter the "budding" group, respectively. The flattened epidermis group showed a significan...

The aim of this research was to study the influence of exposure duration and the spatial-frequency composition of faces in a «same-different» judgment task. Subjects had to match two faces presented successively. The recognition rate depended on the spatial-frequency composition of the target face, and on exposure duration only for high-frequency stimuli. This effect was observed only for durations which were greater than Bloch's psychophysics threshold and only concerned the «same» face pairs. These results are quite consistent with the hypothesis that exposure duration has a differential effect on low and high frequency integration. They are discussed in relation to the single and dual-process models of the «same-different» judgment task (Farell, 1985). Potential consequences on the format of facial representations in memory are proposed

The role of configural information in gender categorisation was studied by aligning the top half of one face with the bottom half of another. The two faces had the same or different genders. Experiment l shows that participants were slower and made more errors in categorising the gender in either half of these composite faces when the two faces had a different gender, relative to control conditions where the two faces were nonaligned or had the same gender. This result parallels the composite effect for face recognition (Young et al, 1987 Perception16 747–759) and facial-expression recognition (Calder et al, 2000 Journal of Experimental Psychology: Human Perception and Performance26 527–551). Similarly to responses to face identity and expression, the composite effect on gender discrimination was disrupted by inverting the faces (experiment 2). Both experiments also show that the composite paradigm is sensitive to general contextual interference in gender categorisation.

Now day’s security of any area is most important task. At different places security required authentication for that purpose biometric system is commonly used. Biometrics is the most suitable means of identifying and authenticating individuals in a reliable and fast way through unique biological characteristics. In this paper we study some concepts which are related to biometrics like meaning of biometrics, history of biometrics, biometric verification and identification, Biometric Recognition techniques, uses, advantages, disadvantages of biometrics.

In the current research work we are focus different types of biometric system with its advantages and disadvantageous.

We report an eight years female child with clinical and molecular cytogenetic findings consistent with CATCH 22 syndrome characterized by cardiac defect, typical facial dysmorphism, mental deficiency and chromosome 22 q11.2 deletion. Interphase FISH with 22q 11.2 probe demonstrated hemizygous deletion in 98.5% nuclei. Interphase FISH for diagnosis of CATCH 22 syndrome has not been reported previously from India to our knowledge.

The aim was to develop a comprehensive screening instrument for evaluation of orofacial dysfunction that was easy to perform for different health professionals without special equipment. The Nordic Orofacial Test--Screening (NOT-S), consisting of a structured interview and clinical examination,was developed with a picture manual illustrating the different tasks in the examination. It was first tested in a Swedish version, and later translated to other Nordic languages, and to English. The interview reflected six domains, (I) Sensory function, (II) Breathing, (III) Habits, (IV) Chewing and swallowing, (V) Drooling, and (VI) Dryness of the mouth, and the examination included six domains representing (1) The face at rest, and tasks regarding (2) Nose breathing, (3) Facial expression, (4) Masticatory muscle and jaw function, (5) Oral motor function, and (6) Speech. One or more "yes" for impairment in a domain resulted in one point (maximum NOT-S score 12 points). The mean NOT-...
