Balaji Manohar, Dhritiman Baidya, Neema Shetty, Aditi Mathur, Barkha Makhijani
The Calcifying Odontogenic Cyst was first described as a distinct clinicopathologic entity by Gorlin and his colleagues in 1962. Gold (1963) chose a similar, but not identical term for the lesion, namely 'keratinizing and calcifying odontogenic cyst'. The calcifying cystic odontogenic tumor (CCOT) is a new designation of calcifying odontogenic cyst (COC) recommended by the 2005 classification of the World Health Organization (WHO). The calcifying odontogenic cyst is not a common lesion; the dentinogenic ghost cell tumor is even less common and should be considered rare...

Biomaterials have been attracting attention as a useful building block for biocompatible and bioresorbable electronics due to its non-toxic property and solution processabillity. In this work, we report the integration of biocompatible keratin from human hair as dielectric layer for organic thin-film transistors (TFTs), with high performance, flexibility and transient property. The keratin dielectric layer exhibited a high capacitance value above 1.27 μF/cm2 at 20 Hz due to the formation of electrical double layer...

No expression and distribution patterns of polyamines (PAs), spermine, spermidine, and their precursor putrescine in mammalian hair follicle are available, although polyamines are known to correlate well with hair growth and epidermal tumor genesis. Immunohistochemistry (IHC) using our original two monoclonal antibodies (mAbs) ASPM-29 specific for spermine or spermidine, and APUT-32 specific for putrescine allowed us to detect immunoreactivity for polyamines in hair follicles from normal adult rats. A wide range of immunoreactivity for the total spermine and spermidine was observed in the compartments of hair follicle: The highest degree of immunoreactivity for polyamines was observed in the matrix, in the Huxley's layer, in the deeper Henle's layer, and in the cuticle of the inner root sheath/the hair cuticle, while moderate immunoreactivity existed in the lower-to-mid cortex and the companion layer, followed by lower immunoreactivity in the outer root sheath, including the bulge region and in the deeper medulla, in which the immunoreactivity was also evident in their nuclei...

Minoxidil is approved for topical treatment of androgenic alopecia but hampered by poor cutaneous absorption. Recently, the randomized control trial showed that hair loss treatment of minoxidil was improved by co-application of the anti-androgen, Curcuma aeruginosa Roxb. extract. Here, we aimed to show that the apparent synergism arises from improved cutaneous penetration of minoxidil by bioactive compound, germacrone or C. aeruginosa (as an n-hexane extract, or essential oil). The partition coefficient of germacrone was determined by HPLC...

BACKGROUND: Fibroblast growth factor 18 (FGF18) is one of the key factors in human signaling pathways and has been reported to be associated with the formation of various tissues. Additionally, FGF18 has been reported to maintain the telogen stage of the hair cycle, and its over-expression has also been observed in cancer cells. HYPOTHESIS/PURPOSE: We searched for natural compounds that inhibit the expression of FGF18 expression in vitro and evaluated their inhibitory mechanisms...

OBJECTIVE: Primary blast-induced mild traumatic brain injury (mTBI) is an injury experienced during modern warfare due to exposure to the pressure waves produced by the detonation of explosives. With virtually no apparent physical damage or symptoms presented, there is a need for more objective and accessible mTBI biomarkers posing minimal invasiveness risk. METHODS: We measured the transcriptomic sensitivity of the hair follicles in relation to the severity of primary blast-derived TBI...

Ultraviolet (UV)-absorbing chemicals (UV filters) are used in personal care products for the protection of human skin and hair from damage by UV radiation. Although these substances are released into the environment in the production and consumption processes, little is known about their ecotoxicology effects. The acute toxicity and potential ecological risk of UV filters benzophenone-3 (BP-3) and benzophenone-4 (BP-4) on Chlorella vulgaris, Daphnia magna, and Brachydanio rerio were analyzed in the present study...

Hair follicle morphogenesis is triggered by reciprocal interactions between hair follicle germ (HFG) epithelial and mesenchymal layers. Here, we developed a method for large-scale preparation of HFGs in vitro via self-organization of cells. We mixed mouse epidermal and mouse/human mesenchymal cells in suspension and seeded them in microwells of a custom-designed array plate. Over a 3-day culture period, cells initially formed a randomly distributed single cell aggregate and then spatially separated from each other, exhibiting typical HFG morphological features...

BACKGROUND: Conceptualizations of emotion dysregulation (ED) and body-focused repetitive behavior disorders (BFRBDs) imply that ED may be a central component of BFRBDs as well as a factor that distinguishes BFRBDs from non-impairing, subclinical body-focused repetitive behaviors (BFRBs). The current study empirically tested these observations. METHODS: One hundred thirty-eight undergraduates (of 1900 who completed a screening survey) completed self-report measures assessing four emotion regulation (ER) deficits hypothesized to underlie ED (alexithymia, maladaptive emotional reactivity, experiential avoidance, and response inhibition when distressed); 34 of these participants had BFRBDs, 64 had subclinical BFRBs, and 42 were unaffected by BFRBs...

Hair analysis has notably expanded its application as a bio-monitor for drug or toxicant exposure. Hair pigmentation is proposed as a major factor affecting drug incorporation into hair; however, the mechanisms underlying the incorporation of drugs into hair are still unclear. In the present study, the effect of hair pigmentation on drug incorporation into hair was examined using rats carrying hair with different melanin status and human cells (SK-Mel-28 cells, HaCaT cells and the co-cultured HaCaT cells with SK-Mel-28 cells) representing the main pigmentary unit in hair...

Sahar E Abo-Neima
Cancer treatment is one of the main challenges that face the scientific centers all over the world. The cancer incidence percentage increases year after year. The most used treatment for cancer is chemotherapy which is an application of systemic cytotoxic drug inside the patient. There are two main problems in chemotherapy that the cytotoxic drug is given systematically and cannot be localized in the tumor region in most cases that lead to killing the cancer cells as well as normal cells; and that cause the chemotherapy side effects like anemia, decrease in all blood cells count and platelets, nausea, vomiting, diarrhea, hair and nails loss and may cause a kind of blood toxicity...

In the present investigation, we studied the development of 6 physically aggressive behaviors in infancy and toddlerhood, posing 3 questions (a) How do the prevalences of individual physically aggressive behaviors change from 8, 15, and 24 months? (b) Are there groups of children who show distinctive patterns in the way individual physically aggressive behaviors develop over time? (c) What are the behavioral pathways leading from 8- to 24-month acts of physical aggression? Mothers and fathers (N = 272) from a moderately at-risk population reported on their children's physical aggression at each time point...

While chronic early stress increases child susceptibility to psychopathology, risk and resilience trajectories are shaped by maternal social influences whose role requires much further research in longitudinal studies. We examined the social transmission of risk by assessing paths leading from war-exposure to child symptoms as mediated by 3 sources of maternal social influence; stress physiology, synchronous parenting, and psychiatric disorder. Mothers and children living in a zone of continuous war were assessed in early childhood (1...

The presence of history of redness and swelling of toe in an infant without history of trauma is typical of hair threat tourniquet syndrome. The treatment simply involves incision and removal of hair fibers. Physicians should be aware of this syndrome because early diagnosis and treatment avoid serious complications.
