Abstract
The present research was aimed to develop a terbinafin hydrochloride (TH)-encapsulated solid lipid nanoparticles (SLNs) hydrogel for improved antifungal efficacy. TH-loaded SLNs were obtained from glyceryl monostearate (lipid) and Pluronic® F68 (surfactant) employing high-pressure homogenization. The ratio of drug with respect to lipid was optimized, considering factors such as desired particle size and highest percent encapsulation efficiency. Lyophilized SLNs were then incorporated in the hydrogel prepared from 0.2–1.0% w/v carbopol 934P and further evaluated for rheological parameters. The z-average, zeta potential and polydispersity index were found to be 241.3 nm, −15.2 mV and 0.415, respectively. The SLNs show a higher entrapment efficiency of about 98.36%, with 2.12 to 6.3602% drug loading. SEM images, XRD and the results of the DSC, FTIR show successful preparation of SLNs after freeze drying. The TH-loaded SLNs hydrogel showed sustained drug release (95.47 ± 1.45%) over a period of 24 h. The results reported in this study show a significant effect on the zone of inhibition than the marketed formulation and pure drug in Candida albicans cultures, with better physical stability at cooler temperatures. It helped to enhance skin deposition inthe ex vivostudy and improved, in vitro and in vivo, the antifungal activity.

Abstract
Self-assembled nanocarriers (SANs) as a novel colloidal controlled delivery for docetaxel trihydrate (DTX) were engineered by high-pressure homogenization method to overcome the several clinical problems. Drug-excipient compatibility was studied using DSC and FTIR spectroscopy. The fabricated SANs was characterized by particle size, zeta potential, and SEM. QbD based central composite design of experiment was employed for formula optimization. The cell viability of DTX-hydroalcoholic solution (DTX-HA) and DTX-loaded SANs has been determined in MDA-MB-231 cell line by MTT assay. The stability study of selected SANs formulations were carried out at various storage conditions as per ICH guidelines. The summary of results obtained shows high drug content with higher entrapment efficiency (91.23 ± 3.41% w/w) of DTX-loaded SANs. It shows diffusion controlled release of DTX over the period of 12 h which is higher than DTX-HA solution, releases the DTX within 4 h. The MTT assay expressed lower cellular viability and improved cell inhibition leads to increase cytotoxicity of formulations towards cells. The stability study reveals stability of DTX-loaded SANs formulations at various storage conditions over a period of three months. The strong experimental evidence confirms the SANs as an effective approach to formulate the controlled delivery system of antineoplastics with improved stability.

Abstract
Exaggerated thoughts, diminished mood and impaired cognition are the hallmarks of the schizophrenia-like condition. These symptoms are attributed to the dysregulation of dopamine and glutamate signaling in the brain. Since cocaine- and amphetamine-regulated transcript peptide (CART) modulates actions of dopamine as well as glutamate, we tested the role of this peptide in MK-801-induced schizophrenic dementia-like condition. MK-801-treated rats were allowed to interact with conspecific juvenile and tested for short-term (30-min) and long-term (24-h) social memory acquisition and recall. While MK-801 impaired the social interaction with a juvenile, the behavior was restored in CART [intracerebroventricular (icv) or intra-ventral tegmental area (VTA)] pre-treated animals. This action of CART was blocked by SCH23390 (dopamine D1 receptor antagonist) administered directly into the prefrontal cortex (PFC). Application of neuronal tracer Di-I in the PFC retrogradely labeled dopamine cells of the VTA, which in turn seem to receive CARTergic innervation. A significant increase in CARTimmunoreactivity was evidenced in the VTA, PFC and accumbens of the animals allowed to interact with a juvenile. However, MK-801 treatment attenuated the peptide expression and induced social memory deficits. The schizophrenic dementia-like symptoms following antagonism of glutamatergic receptors may be attributed to the reduced dopamine activity in the mesocortical system. We suggest that CART may, positively modulate the dopamine system to alleviate cognitive deficits associated with schizophrenia.

Abstract
Although cocaine- and amphetamine-regulated transcript peptide (CART) is detected in several cortical and subcortical areas, its role in higher functions has been largely ignored. We examined the significance of CART in memory formation and tested if the downstream actions of CART involve N-methyl-d-aspartate (NMDA) activated extra-cellular signal-regulated kinase (ERK). Newly formed memory was evaluated using novel object recognition test consisting of familiarization (T1) and choice trials (T2). The choice trials were performed at two time points: 30-min (T230-min ) and 24-h (T224-h ) postacquisition. In choice trial (T230-min ), vehicle control rats explored the novel object for significantly longer duration than the familiar object indicating intact memory formation. However, CART-antibody, U0126 [ERK antagonist, both via intracerebroventricular (icv) or intrahippocampal (ih) route] or MK-801 (NMDA antagonist; intraperitoneal) treated rats spent less time exploring novel objects; CART peptide (icv or ih) was ineffective. During choice trial at T224-h , a significant decrease in novel object exploration time was noticed in vehicle control rats suggesting amnesia. However, treatment with CART, prior to familiarization trial (T1), promoted exploration of the novel object even at T224-h . Pretreatment with U0126 or MK-801 blocked pro-cognitive-like effect of CART suggesting involvement of NMDA-ERK pathway in CART's action. Animals subjected to the object familiarization trial showed a drastic increase in the CART-immunoreactivity in the cells of cornu ammonis 3 and polymorph layer of dentate gyrus, and fibers within ento- (ENT) and peri-rhinal (PRH) cortices. Western blot analysis revealed that CART treatment significantly up-regulated the expression of phospo-ERK1/2 in hippocampus, ENT and PRH. This effect was attenuated following pretreatment with U0126 or MK-801, suggesting the activation of ERK signaling cascade through NMDA receptors. Thus, CART system seems to play an important role in recognition memory and that these effects may be mediated by NMDA receptors-ERK signaling in the ENT/PRH-hippocampal circuit. © 2016 Wiley Periodicals, Inc.

Abstract
Binge eating (BE) disrupts feeding and subverts reward mechanism. Since cocaine- and amphetamine-regulated transcript peptide (CART) mediates satiety as well as reward, its role in BE justifies investigation. To induce BE, rats were provided restricted access to high fat sweet palatable diet (HFSPD) for a period of 4 weeks. Immunoreactivity profile of the CART elements, and accompanying neuroplastic changes were studied in satiety- and reward-regulating brain nuclei. Further, we investigated the effects of CART, CART-antibody or rimonabant on the intake of normal chow or HFSPD. Rats fed on HFSPD showed development of BE-like phenotype as reflected by significant consumption of HFSPD in short time frame, suggestive of dysregulated satiety mechanisms. At the mid-point during BE, CART-immunoreactivity was significantly increased in hypothalamic arcuate (ARC), lateral (LH), nucleus accumbens shell (AcbSh) and paraventricular nucleus of thalamus (PVT). However, for next 22-h post-binge time-period, the animals showed no interest in food, and low CART expression. Pre-binge treatment with rimonabant, a drug recommended for the treatment of BE, produced anorexia, increased CART expression in ARC and LH, but not in AcbSh and PVT. Higher dose of CART was required to produce anorexia in binged rats. While neuronal tracing studies confirmed CART fiber connectivity from ARC and LH to AcbSh, increase in CART and synaptophysin immunostaining in this pathway in BE rats suggested strengthening of the CART connectivity. We conclude that CART bearing ARC-LH-PVT-AcbSh reward circuit may override the satiety signaling in ARC-PVN pathway in BE rats.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Chenopodium album L. (C. album) is commonly known as Bathua in Hindi (Family: Chenopodiaceae). Traditionally, the plant is used as a laxative, diuretic, sedative and the infusion of the plant is used for the treatment of rheumatism. However, no scientific validation is available on the antirheumatic potential of the plant. In the present investigation, role of NF kappa B (NFκB) in the antiarthritic potential of extracts of aerial parts of Chenopodium album was explored and evaluated. METHODS The defatted aerial parts of Chenopodium album were successively extracted with ethylacetate, acetone, methanol and 50% methanol to study their antioxidant capacity followed by antiarthritic potential using Complete Freund׳s adjuvant (CFA) induced arthritis model in rats. The polyphenol, flavonoid and flavanone contents of different extracts were quantified and correlated with their antioxidant capacity, antiarthritic activity and NFκB inhibition potential. RESULTS The experimental data indicated that the acetone extract of Chenopodium album (ACCA) has shown significant reduction in rat paw edema (80.13%) at dose level of 200 mg/kg per oral in 21 days of this study. On 22nd day, hematological and biochemical parameters were estimated and it was observed that the altered hematological parameters (Hb, RBC, WBC and ESR), biochemical parameters (Serum creatinine, total proteins and acute phase proteins) and loss in body weight in the arthritic rats were significantly brought back to near normal level by the ACCA extract. ACCA extract significantly decreased the NFκB expression in paraventricular nucleus of hypothalamus and this effect is comparable with standard indomethacine in CFA treated rats. The polyphenolic and flavonoid content of different extracts were in the range of 14.56±0.21-42.00±0.2 mg (gallic acid equivalent/g extract) and 2.20±0.003-7.33±0.5 mg (rutin equivalent/g extract) respectively. CONCLUSION The antiarthritic activity possessed by ACCA extract can be correlated directly to its antioxidant potential, high flavonoidal content achieved by successive extraction and its capacity to inhibit the NFκB protein, as proven by immunohistochemistry study.

Abstract
In the present study, modulation of anxiolytic action of agmatine by neuropeptide Y (NPY) in the central nucleus of amygdala (CeA) is evaluated employing Vogel's conflict test (VCT) in rats. The intra-CeA administration of agmatine (0.6 and 1.2µmol/rat), NPY (10 and 20pmol/rat) or NPY Y1/Y5 receptors agonist [Leu(31), Pro(34)]-NPY (30 and 60pmol/rat) significantly increased the number of punished drinking licks following 15min of treatment. Combination treatment of subeffective dose of NPY (5pmol/rat) or [Leu(31), Pro(34)]-NPY (15pmol/rat) and agmatine (0.3µmol/rat) produced synergistic anxiolytic-like effect. However, intra-CeA administration of selective NPY Y1 receptor antagonist, BIBP3226 (0.25 and 0.5mmol/rat) produced anxiogenic effect. In separate set of experiment, pretreatment with BIBP3226 (0.12mmol/rat) reversed the anxiolytic effect of agmatine (0.6µmol/rat). Furthermore, we evaluated the effect of intraperitoneal injection of agmatine (40mg/kg) on NPY-immunoreactivity in the nucleus accumbens shell (AcbSh), lateral part of bed nucleus of stria terminalis (BNSTl) and CeA. While agmatine treatment significantly decreased the fibers density in BNSTl, increase was noticed in AcbSh. In addition, agmatine reduced NPY-immunoreactive cells in the AcbSh and CeA. Immunohistochemical data suggest the enhanced transmission of NPY from the AcbSh and CeA. Taken together, this study suggests that agmatine produced anxiolytic effect which might be regulated via modulation of NPYergic system particularly in the CeA.

Swiss-albino mice were subjected to experimental spinal cord injury (ESCI) and treated with serotonergic antagonist, ritanserin, alone or in combination with α-MSH, and the locomotor recovery was investigated. ESCI was induced at thoracic T(10-12) level by compression method. Motor function score (0-10) of each mouse was monitored prior to, and on days 1, 4, 7, 10 and 14 following ESCI. Untreated ESCI animals showed almost normal hind limb motor function by 14days. Similar degree of recovery was observed on day 10 in animals given α-MSH or ritanserin. However, in animals treated with both agents, comparable recovery was observed on day 4. While histological examination of the spinal cord following ESCI showed demyelination, necrosis and cyst formation, treatment with ritanserin, alone and in combination with α-MSH, significantly prevented the tissue damage. We suggest that early antagonism of serotonergic 5-HT(2a/2c) receptors may potentiate the neurotropic and locomotor recovery activity of α-MSH.
