Abstract
The climate and, hence, potential habitability of a planet crucially depends on how its atmospheric and ocean circulation transports heat from warmer to cooler regions. However, previous studies of planetary climate have concentrated on modeling the dynamics of atmospheres, while dramatically simplifying the treatment of oceans, which neglects or misrepresents the effect of the ocean in the total heat transport. Even the majority of studies with a dynamic ocean have used a simple so-called aquaplanet that has no continental barriers, which is a configuration that dramatically changes the ocean dynamics. Here, the significance of the response of poleward ocean heat transport to planetary rotation period is shown with a simple meridional barrier--the simplest representation of any continental configuration. The poleward ocean heat transport increases significantly as the planetary rotation period is increased. The peak heat transport more than doubles when the rotation period is increased by a factor of ten. There are also significant changes to ocean temperature at depth, with implications for the carbon cycle. There is strong agreement between the model results and a scale analysis of the governing equations. This result highlights the importance of both planetary rotation period and the ocean circulation when considering planetary habitability.

Abstract
Variable fluorescence (Fv), i.e., Fv = Fm - F0 where F0 is the minimal fluorescence and Fm the maximum fluorescence, and difference Fourier transform infrared (FT-IR) spectroscopy were used to study the effect of heat stress in the 25-55 °C range on photosystem II (PSII) structure and function. First, the Fv intensity reflects accurately the changes in the number of open photochemical centers in PSII. Secondly, the use of Fv in combination with FT-IR spectroscopy can disclose structure-function correlations in the heat inactivation of the PSII complex. Analysis of the midpoint temperatures of thermal denaturation, i.e., 50% inactivation, reported so far in investigations of the thylakoid membrane components has revealed that most of the thermal transitions attributed to PSII are in the 39 -46 °C range. In this work, it is shown specifically that the midpoint temperature of PSII inactivation is at about 40 °C. Moreover, it was clearly demonstrated that the heat-induced changes above 40 °C are the result of a marked decrease in the number of open photochemical centers in PSII. It was also seen that above this same temperature the loss of photochemical centers has its structural counterpart in overall modifications of the secondary structures of the PSII proteins resulting from the decrease in the α-helix content concomitant with the increase in extended chain (β-strand) conformations. In brief, a novel finding reported here is that the number of open photochemical centers in PSII is dependent on a dynamic equilibrium between the contents of the PSII proteins in α-helix and extended chains (β-strands), but not in β-sheets and β-turn structures except for the antiparallel-β-sheet conformations. This therefore associates the thermal inactivation of the photochemical centers in photosystem II with distinct conformational changes in the proteins of the PSII supramolecular complex. In the particular context of the present study, these findings constitute a significant contribution to the investigation of structure-function correlations in the photosynthetic membrane. In a broader context, this information might be essential for the comprehension of the molecular arrangements or local structure order that are involved directly or indirectly in biological catalysis

Abstract
Two siblings with a severe multiorgan polycystic disease presenting in the neonatal period were identified. Their genetic testing identified compound heterozygous NPHP3 gene mutations, parents being heterozygous carriers. The mutations included a splice-site (c.958-2A>G) and a missense mutation (c.2342G>A; p.G781D), both being extremely rare. NPHP3 encodes for nephrocystin 3 present on the cilia-centrosome complex. We hypothesize that these mutations lead to defective cilia-based signaling, required for normal development of the renal, pancreatic, biliary and portal system. This report outlines a rare neonatal ciliopathy presentation of NPHP3 mutations leading to severe multiorgan failure in two siblings.

Abstract
Radial nerve is usually a branch of the posterior cord of the brachial plexus. It innervates triceps, anconeous, brachialis, brachioradialis, extensor carpi radialis longus muscles and gives the posterior cutaneous nerve of the arm, lower lateral cutaneous nerve of arm, posterior cutaneous nerve of forearm; without exhibiting any communication with the medial cutaneous nerve of forearm or any other nerve. We report communication between the radial nerve and medial cutaneous nerve of forearm on the left side in a 58-year-old male cadaver. The right sided structures were found to be normal. Neurosurgeons should keep such variations in mind while performing the surgeries of axilla and upper arm.

Abstract
Inca bones are accessory bones found in neurocranium of human skulls. Occurrence of Inca bones is rare as compared
to other inter sutural bones such as wormian bones. These Inca ossicles are regarded as variants of the normal. The
reporting of such occurrences is inadequate from Central India. Objectives: To find the incidence of Inca variants in Central India. Materials and Methods: In the present study, 380 dried adult human skulls were examined. All specimen samples were procured from various Medical colleges of Central India. They were analyzed for gross incidence, sexual dimorphism and number of fragments of Inca bones. Results: Gross incidence of Inca bones was found to be 1.315 %. Incidence rate was higher in male skulls than female skulls (male: 1.428%; female: 1.176%). The Inca bones frequently occurred signally. Out of the five observed Inca ossicles, two were fragmented. Conclusions: This data gives idea regarding gross incidence, sexual dimorphism and number of fragments of Inca bones in neurocranium of human skulls from Central India. The knowledge of this variable is useful for neurosurgeons, anthropologists and radiologists.

Abstract
Numerical simulations were carried out to quantify the reflection and transmission characteristics of the fundamental Lamb modes propagating in aluminium sub-plates, which are formed due to a semi-infinite horizontal crack. It was observed that, a Lamb mode propagating in a sub-plate when incident at the edge of a crack, undergoes reflection and transmits through the main plate, as well as the other sub-plate. The mode transmitted through the sub-plate has been termed the 'Turning Lamb Mode' (TLM). Furthermore, a mode converted mode also propagates along with the TLM. This mode has been termed the 'Mode Converted Turning Lamb Mode' (MCTLM). Reflection and transmission characteristics of the fundamental Lamb modes in aluminium sub-plates were studied at frequencies 150 kHz, 175 kHz, and 200 kHz. Experiments conducted to validate the observations made in numerical simulations, confirmed that the transmission and reflection characteristics depend on the thickness ratio. From this study it is surmised that when a Lamb mode propagates through a plate containing horizontal crack, the TLM and the MCTLM start propagating from one sub-plate to the other at the rear edge of the crack and amplitude of these modes depends on the location of the crack across the plate thickness.

Abstract
Background: Fine needle aspiration cytology (FNAC) is extensively used in the diagnosis of various clinically palpable lesions of breast and salivary glands. Much interest has been gained in mucosubstances produced in tumors arising from these organs. Aims: To evaluate the utility of Periodic acid Schiff with diastase (PAS-D) and Alcian blue (AB) staining pattern on fine needle aspirates of breast and salivary gland neoplasms. Materials and Methods: Seventy-five cases of different neoplasm of breast and salivary gland were studied. The staining pattern of PAS-D and AB stains on smears of these neoplasm were observed. Results: Among cases of neoplasms of breast, intracytoplasmic PAS-D positive globules were restricted to carcinoma except in one case where PAS-D-positive globules were seen in fibroadenoma. The background substance of both mucinous carcinoma and fibroadenoma with myxoid change stained positive with PAS-D, but the pattern was different. The cases of pleomorphic adenoma and mucoepidermoid carcinoma of salivary gland showed intracytoplasmic PAS-D-positive globules. The cases of pleomorphic adenoma showed stromal positivity which was not seen in basal cell adenoma on smears. Conclusion: Intracytoplasmic PAS-D-positive globules may be useful in differentiating benign and malignant lesions of breast. The presence of PAS-D positive granules are useful in differentiating various lesions of salivary glands. AB staining of stromal fragments in pleomorphic adenoma is useful in differentiating it from basal cell adenoma.

Abstract
The physicochemical properties of lentil starch were measured and linked up with its functional properties and compared with those of corn and potato starches. The amylose content of lentil starch was the highest among these starches. The crystallinity and gelatinization enthalpy of lentil starch were the lowest among these starches. The high amylose: amylopectin ratio in lentil starch resulted into low crystallinity and gelatinization enthalpy. Gelatinization and pasting temperatures of lentil starch were in between those of corn and potato starches. Lentil starch gels showed the highest storage modulus, gel strength and pasting viscosity than corn and potato starch gels. Peleg's model was able to predict the stress relaxation data of these starches well (R(2)>0.98). The elastic modulus of lentil starch gel was less frequency dependent and higher in magnitude at high temperature (60 °C) than at lower temperature (10 °C). Lentil starch is suitable where higher gel strengthened pasting viscosity are desired.

Abstract
Rapidly progressing mucosal breakdown limits the intestinal preservation time below 10 h. Recent studies indicate that intraluminal solutions containing polyethylene glycol (PEG) alleviate preservation injury of intestines stored in UW-Viaspan. We investigated whether a low-sodium PEG solution is beneficial for intestines stored in histidine-tryptophane-ketoglutarate (HTK) preservation solution. Rat intestines used as control tissue (group 1) were perfused with HTK, groups 2 and 3 received either a customized PEG-3350 (group 2) or an electrolyte solution (group 3) intraluminally before cold storage. Tissue injury, brush-border maltase activity, zonula occludens-1 (ZO-1) and claudin-3 expression in the tight junctions (TJ) were analyzed after 8, 14 and 20 h. We measured epithelial resistance and permeability (Ussing chamber) after 8 and 14 h. Group 2 had superior morphology while maltase activity was similar in all groups. TJ proteins rapidly decreased and decolocalized in groups 1 3; these negative events were delayed in group 2, where colocalization persisted for about 14 h. Intestines in group 2 had higher epithelial resistance and lower permeability than the other groups. These results suggest that a customized PEG solution intraluminally reduces the intestinal preservation injury by improving several major epithelial characteristics without negatively affecting the brush-border enzymes or promoting edema.

Abstract
The role of zinc (Zn) in anxiety, depression and psychosis was studied in rodents. Zn was administered at doses of 15 and 20 mg/kg intraperitoneally for 7 days. Both doses of Zn reduced the immobility time and increased the swimming time in the modified forced swim test. In the elevated plus maze test, increases in the number of open arm entries and time spent in the open arms were observed with both doses of Zn. In the amphetamine (1 and 2 mg/kg subcutaneously) induced locomotor activity test both doses of Zn produced reduction in the total movement time, mean velocity and stereotypic movements. Extrapyramidal symptoms such as catalepsy in animals are usually observed with conventional antipsychotic agents; but in the present study, Zn at doses of 15 and 20 mg/kg did not produce any cataleptic state in mice. The results of the present study demonstrated the anxiolytic, antidepressant and antipsychotic-like effects of Zn metal ion, which may be due to its N-methyl d-aspartate receptor antagonistic activity. Concurrent administration of a lower dose of Zn with standard existing anxiolytic and antidepressant drugs in this study showed potentiating effect, suggesting that Zn could exert beneficial role when prescribed as add-on medicine in the psychiatric illnesses. The results obtained in this study are preliminary, as further research is required to confirm the exact role of Zn metal in the investigated central nervous system disorders.

Abstract
BACKGROUND World Health Organization (WHO) predicts that tobacco deaths in India may exceed 1.5 million annually by 2020. OBJECTIVES The aim of this study was to estimate the prevalence of tobacco use, its influences, triggers, and associated oral lesions among the patients of Rural Dental College and Hospital of Loni, Maharashtra. MATERIALS AND METHODS A hospital based cross-sectional study was conducted from June - December 2010. All the patients from the outpatient department and with tobacco habits were included in the study. Patients were interviewed through a pre-tested structured questionnaire in relation to their tobacco habits, its influences and triggers. Also clinical examination was carried out to check for any tobacco related oral lesions. For the data analysis, Microsoft Excel and chi-square test was used. RESULTS The overall prevalence of tobacco use was 16.38%. Smokeless form of tobacco was more prevalent in both males (81.84%) and females (100%). Majority of the patients (males - 68.22%, females- 90.62%) were light tobacco users. About 76.09% males and 31.25% females admitted that they developed the habit due to initial influence of friends. The most common oral mucosal lesion in both the males (42.20%) and females (11.07%) was tobacco hyperkeratosis. Most common trigger for tobacco use was "work related" (69.14%) in males and "after meals" (53.13%) in females. CONCLUSION Since the number of tobacco users visiting the dental hospital is reasonably high; dentists can contribute to restrain the hazard through community educational activities such as de-addiction counseling of tobacco users to quit the habit.
