Long-term treatment and poor management of psychiatric manifestations in mesial temporal sclerosis leading to suicidality in a young male

Psychiatric disorders including anxiety, psychosis, and aggressive behaviors are frequently diagnosed in patients with epilepsy. In this communication, we report a patients with mesial temporal lobe sclerosis with interictal affective-somatoform (dysphoric) disorders who was never treated for psychiatric manifestations, and who deliberately took a massive dose of phenytoin and phenobarbitone with a motive of suicide, resulting in severe combined toxicity. Such unfortunate incidences may be prevented, and quality of life can be improved with early diagnosis, through the selection of the right antiepileptic drugs, reasonable psychiatric consultation, and appropriate biological and psychological treatments.

Joint effusions and purpura in multiply-transfused adult beta-thalassemia- clinical pointers to diagnosis of scurvy

Periodic transfusions and effective chelation have ensured that thalassemics survive in to adulthood but their life is punctuated by peculiar problems in adulthood. Three cases of scurvy are being reported presenting uniquely as purpura, right hip joint effusion and right knee joint effusion with haemorrhage in prepatellar and retropatellar bursae, respectively over an 18 month period (2009-2010). The first two cases did give a history of gum bleed. None had any coagulation disturbance or transfusion-transmitted infections or connective tissue disorder. All the three cases responded dramatically to vitamin C supplementation. It is imperative to keep in mind that recurrent blood transfusions are associated with a state of subclinical vitamin C deficiency and overt scurvy may manifest as cumulative number of transfusions increase, as in adult thalassemics.

Molecular analysis of dinucleotide microsatellite in growth hormone gene of Asian seabass (Lates calcarifer) from Mumbal, India

In the present study, out of four alleles amplified from seabass (Lates calcarifer) genome inhabiting Mumbai water by PCR using growth hormone (GH) gene-specific primers, two DNA fragments (SGMS1, 233 bp and SGMS2, 239 bp) were eluted from gel, cloned using pTZ57R (2.886 kb) vector into E. coli DH5α, characterized by restriction endonuclease analysis and sequenced by automated DNA sequencer. After blasting and multiple alignment of the above sequences, SGMS1 showed 97% and SGMS2 93.3% homology with promoter region of GH gene containing microsatellite of Australian seabass and 94.6% homology between both the fragments. These sequences SGMS1 and SGMS2 were submitted to NCBI GenBank. On blasting, these sequences with gene databases, SGMS1 and SGMS2 showed partial homologies with Seriola quinqueradiata (26.9%, 12.9%), flounder (15.8%, 15.8%), Oreochromis nilotica (23%, 7.9%), Oreochromis mossambicus (23%, 7.9%) and Danio rerio (8.2%, 7.5%). Critical analysis showed the presence of microsatellite (CA)16 and (CA)19 repeats in fragments SGMS1 and SGMS2, respectively in seabass from Mumbai water in comparison to (CA)14 repeats from the Australian seabass. Further, on sequence comparison, single nucleotide mismatches detected at their several positions in relation to seabass GH gene of Australia. These nucleotide variations detected in SGMS1 and SGMS2 in comparison to those of the Australian seabass may be due to mutations owing to environmental or habitat changes that seem to have definite potentials for development of genetic markers, which would be useful for identification and selection of superior germplasm with desirable commercial traits such as high growth rate.

Production of ligninolytic enzymes by white rot fungi on lignocellulosic wastes using novel pretreatments

Production of extracellular ligninolytic enzymes (laccase and polyphenol oxidase) secreted by three species of white rot fungi (Pleurotus florida, P. flabellatus and P. sajor—caju) under in vivo condition was studied on two lignocellulosic substrates i.e., paddy straw and wheat straw. These lignocellulosic substrates were treated with neem (Azadirachta indica) oil and ashoka (Saraca indica) leaves extract. Between the two lignocellulosic substrates, paddy straw pretreated with neem oil supported maximum activity of laccase and polyphenol oxidase (PPO). The activities of both the enzymes were low on the 5th day of cultivation which increased on the 10th day and reached at peak on the 15th day. Thereafter, there was continuous decrease in the enzymatic activity. Among the three species, P. flabellatus (P3) showed maximum ligninolytic enzymatic activity followed by P. florida (P2)and P. sajor—caju (P1).

Production of cellulolytic enzymes by Pleurotus species on lignocellulosic wastes using novel pretreatments

In the present investigation three species of Pleurotus i.e. P. sajor—caju (P1), P. florida (P2) and P. flabellatus (P3) along with two lignocellulosic substrates namely paddy straw and wheat straw were selected for evaluation of production of extracellular cellulolytic enzymes. During the cultivation of three species of Pleurotus under in vivo condition, the two lignocellulosic substrates were treated with plants extracts (aqueous extracts of ashoka leaves (A) and neem oil (B)), hot water (H) and chemicals (C).Among all treatments, neem oil treated substrates supported better enzyme production followed by aqueous extract of ashoka leaves, hot water and chemical treatment. Between the two substrates paddy straw supported better enzyme production than wheat straw. P. flabellatus showed maximum activity of exoglucanase, endoglucanase and β—glucosidase followed by P. florida and P. sajor—caju.

Community Based Survey on Psychiatric Morbidity in Eastern Nepal

INTRODUCTION

Mental health problem is common and ubiquitous. Mental illness cuts across all sections of society, irrespective of socio-economic status. Recent international survey showed a varying prevalence rates ranged (4.7%- 12.0%). The Community study in Nepal yielded prevalence rate of mental illness at 14.0%.

METHODS

This is a descriptive, epidemiologic study with systematic randomization sampling.

RESULTS

Of 911 respondents majority was married (76.1%), of age group 20-59 yrs. Overall, 113 (12.4%) respondents had at least one psychiatric disorder and the commonest were: Depression, Anxiety disorders, Alcohol use disorders with 1.9% had seizure/epilepsy.

CONCLUSIONS

Community prevalence rate of some common psychiatric disorders is high which calls for special attention to address depressive and alcohol related disorder from all quarters of society particularly from government.

Arcobacter spp. isolated from untreated domestic effluent

Arcobacter butzleri and Arcobacter cryaerophilus were isolated from samples of raw untreated domestic sewage influent from nine separate wastewater treatment facilities in Cheshire, UK. This is the first report of Arcobacter spp. from sewage in the UK and suggests that Arcobacter spp. may be present in the human community.

SIGNIFICANCE AND IMPACT OF THE STUDY

Studies have shown Arcobacter spp. to be present in domestic sewage in several European countries. This study supports previous findings with the first report of Arcobacter spp. in domestic sewage in the UK. This study suggests that Arcobacter spp. is present amongst local human populations, implicating it as an underestimated gastrointestinal pathogen in the UK and contributing to our understanding of this emerging pathogen and its presence within the UK. Providing a confirmation of the presence of Arcobacter in sewage, which supports previous studies, this paper will appeal to fellow researchers of Arcobacter, as well as healthcare and water treatment professionals concerned with microbiology, water safety and gastroenterology, potentially having a wide impact.

Study of Pathway to Care among Patients with Epilepsy

Objective: To assess the pathway to care among patients with epilepsy up to the tertiary care centre Methods: It is a hospital based, cross-sectional descriptive study of 47 patients visiting BPKIHS psychiatry OPD. Written informed consent was taken from the patients and the primary caretaker. A semi structured Performa was used to record the basic sociodemographic details. Pathway Interview Schedule developed by WHO was used to collect the data. Results Majority (66.0%) of subjects were male. Generalized Seizures were most common (76.6%) type of seizure followed by complex-partial seizure (10.6%). More than half (51.1%) first contacted dhami-jhakri for treatment of their illness. About sixty two percent of patients had the first contact with the treatment provider less than 4 yrs ago. Thirty eight percent subjects sought treatment as per advice from the family members while only 2.1% sought treatment as per advice from the healthcare worker. The most common presenting complaints were sudden loss of consciousness in 89.4%of patients. In majority of patients (57.4%), problem arised ≤ 4yrs back. Significant high numbers of patients (51.1%) were prescribed alternative forms of treatment like herbal medications, talisman, offerings and sacrifices and jhadphook for their presenting problem. About eighty seven percent patients had to travel ≤12 hours for the treatment while 10.7% had to travel a distance of >24 hrs for treatment. The mean duration that one had to travel for seeking treatment was 7.95±14.58 hours. It was found that the mean duration that one patient spend before coming to a hospital for modern treatment was 5.64 months. Conclusions People suffering from epilepsy are still using the traditional healing practices leading to delay in the patient care. These findings call for a comprehensive educational program that can remove the misconcepts regarding the illness.

Chitosan-transition metal ions complexes for selective arsenic(V) preconcentration

Chitosan is naturally occurring bio-polymer having strong affinity towards transition metal ions. Chitosan complexed with transition metal ions takes up inorganic arsenic anions from aqueous medium. In present work, As(V) sorption in the chitosan complexed with different metal ions like Cu(II), Fe(III), La(III), Mo(VI) and Zr(IV) were studied. Sorptions of As(V) in CuS embedded chitosan, (3-aminopropyl) triethoxysilane (APTS) embedded chitosan, epichlorohydrin (ECH) crosslinked chitosan and pristine chitosan were also studied. (74)As radiotracer was prepared specifically for As(V) sorption studies by irradiation of natural germanium target with 18 MeV proton beam. The sorption studies indicated that Fe(III) and La(III) complexed with chitosan sorbed 95 ± 2% As(V) from aqueous samples in the pH range of 3-9. However, Fe(III)-chitosan showed better sorption efficiency (91 ± 2%) for As(V) from seawater than La(III)-chitosan (80 ± 2%). Therefore, Fe(III)-chitosan was selected to prepare the self-supported membrane and poly(propylene) fibrous matrix supported sorbent. The experimental As(V) sorption capacities of the fibrous and self-supported Fe(III)-chitosan sorbents were found to be 51 and 109 mg g(-1), respectively. These materials were characterized by XRD, SEM and EDXRF, and used for preconcentration of As(V) in aqueous media like tap water, ground water and seawater. To quantify the As(V) preconcentrated in Fe(III)-chitosan, the samples were subjected to instrumental neutron activation analysis (INAA) using reactor neutrons. As(V) separations were carried out using a two compartments permeation cell for the self-supported membrane and flow cell using the fibrous sorbent. The total preconcentration of arsenic content was also explored by converting As(III) to As(V).

Impacts of increasing ozone on Indian plants

Increasing anthropogenic and biogenic emissions of precursor compounds have led to high tropospheric ozone concentrations in India particularly in Indo-Gangetic Plains, which is the most fertile and cultivated area of this rapidly developing country. Current ozone risk models, based on European and North American data, provide inaccurate estimations for crop losses in India. During the past decade, several ozone experiments have been conducted with the most important Indian crop species (e.g. wheat, rice, mustard, mung bean). Experimental work started in natural field conditions around Varanasi area in early 2000's, and the use of open top chambers and EDU (ethylene diurea) applications has now facilitated more advanced studies e.g. for intra-species sensitivity screening and mechanisms of tolerance. In this review, we identify and discuss the most important gaps of knowledge and future needs of action, e.g. more systematic nationwide monitoring for precursor and ozone formation over Indian region.

A Strategic Application of Fast Fourier Transform as a Novel Tool to Evaluate the Extent of Neuronal Insult in Rat Model of Focal Cerebral Ischemia

The present work envisages mathematical modeling of induced focal cerebral ischemia in animal model using EEG data with the help of Fast Fourier Transformation method. Amongst several analysis methods, spectral analysis methods are important because it detects the frequencies and characteristics changes of brain waveforms depending on the brain function affected from disorders and physiological state. There are many applications of FFT, and the most important being that it is one of the basic conventional spectral analysis methods. However, it has some limitations, for instance, it adds contributions in the low frequency region which are not present in the original signal, and necessitates the use of windowing for decreasing the error rate. The present analysis was undertaken to ensure actual correlation of the different mathematical paradigms. EEG data were obtained from different regions of rat brain and were processed by FFT modeling in MATLAB platform. The assessment of long lasting functional outcome and to prevalent classical approach to study stroke was necessitated and therefore highly recommended to evaluate the efficacy of therapeutic strategies in relation to EEG in animal model of brain stroke. This mathematical modeling specifically Power Spectrum Density analysis was done to correlate the different prevalent condition of rat brain function.

Single nucleotide polymorphisms in caprine calpastatin gene

The calpains and calpastatin (CAST) make up a major cytosolic proteolytic system, the calpain-calpastatin system, found in mammalian tissues. The relative levels of the components of the calpain-calpastatin system determine the extent of meat tenderization during postmortem storage. Calpastatin (CAST) is a protein inhibitor of the ubiquitous calcium-dependent proteases-micro-calpain and m-calpain. Polymorphisms in the bovine, ovine and pig CAST gene have been associated with meat tenderness but little is known about how caprine CAST gene may affect goat meat quality traits. In this study we selected different parts of the CAST gene: 1) that have been previously reported to be polymorphic, intron 5 and 12 and 3'UTR; 2) first time explored (exon 3, 7 and 8 and part of intron 7 and 8) to investigate polymorphic status of caprine CAST gene. Using comparative sequencing ten novel SN Ps located in exon 3 and intron 5, 7 and 8 were identified. Previously reported SNPs in intron 5, 3'UTR and intron 12 were absent. Sequence analysis revealed a non synonymous amino acid variation in exon 3, which would result in Lys/Arg substitution in the corresponding protein sequence. Considerable variation was detected in intronic regions. Twenty-four InDel were also recognized in intronic regions (15) and 3'UTR (9). All the sequences shared high homology with published bovine and ovine sequences. Three PCR-RFLP loci have been established for further analyzing genetic polymorphism in indigenous goats.

Antifungal and antioxidative potential of oil and extracts derived from leaves of Indian spice plant Cinnamomum tamala

Plant—based antimicrobials and antioxidants represent a vast untapped source for medicines and food supplements and hence have enormous therapeutic potential. Present work reports the fungicidal potential of Cinnamomum tamala Nees & Eberm (Lauraceae) leaf oil against five food spoilage and pathogenic fungi. In addition antioxidant efficacy of seven different solvent extracts derived from leaf was also evaluated using in vitro models. The oil demonstrated potent antifungal activity against Aspergillus niger, A. fumigatus, Candida albicans, Rhizopus stolonifer and Penicillium spp. in agar diffusion assay. Zone of inhibition ranged from 17-25 mm. The MFC values of oil against all the test fungi were found to be 230μg/ml. Phytochemicals present in C. tamala leaf were extracted in several solvents for assessing their effect in oxidative defense. The extracts exhibited appreciable antioxidant activity in β-carotene bleaching assay and reducing power assay. The antioxidative activities of extracts were compared with the activities of standard antioxidant compounds BHA and ascorbic acid. Petroleum ether, ethanol, acetone and chloroform extracts exhibited about 30-67% antioxidant activity in β-carotene bleaching assay. Aqueous and ethanol extracts exhibited better reducing power which increased gradually with increasing amount of the extract concentration showing dose dependent response. Results indicated that natural phytochemicals present in C. tamala leaf extracts have potential to prevent growth of food spoilage/pathogenic fungi. In addition they also have capability to mitigate the oxidative stress by antioxidant response.

Extracellular xylanase production by Pleurotus species on lignocellulosic wastes under in vivo condition using novel pretreatment

The production of extracellular xylanase by three species of Pleurotus species i.e. P. florida, P. flabellatus and P. sajor caju was studied under in vivo condition during their cultivation on pretreated lignocellulosic wastes. Neem (Azadirachta indica) oil and ashoka (Saraca indica) leaves extract were used for pretreatment of paddy straw and wheat straw. Between these two wastes, paddy straw pretreated with neem oil, supported better xylanase production than wheat straw. Initially, xylanase production was low but it increased in subsequent days and reached at peak on 25th day of cultivation of Pleurotus species. Thereafter, there was decrease in the activity of the enzyme. On 25th day of incubation P. florida produced maximum xylanase on neem oil pretreated paddy straw i.e. 10.59 Uh—1ml—1. Among the three species, P. florida showed maximum enzyme activity followed by P. flabellatus and P. sajor caju.

Protective efficacy of Solanum xanthocarpum root extracts against free radical damage: phytochemical analysis and antioxidant effect

Free radicals have been implicated in many diseases. They attack biological macromolecules in healthy human cells and cause protein and DNA damage along with lipid peroxidation. Present study reports the phytochemical analysis as well as free radical scavenging and antioxidant activities of Solanum xanthocarpum root extracts. Tannins, flavonoids, terpenoids, alkaloids, saponins and steroids were present in different extracts. Total flavonoid content in extracts was quantified and maximum contents were found in ethyl acetate fraction followed by chloroform and ethyl alcohol fractions, respectively. Dose dependent response was observed in metal ion chelating activity of extracts. Comparatively better chelating activity was found in polar extracts. Most of the extracts exhibited significant free radical scavenging activity in DPPH radical scavenging assay. Ethanolic and aqueous extracts accounted for about 40—50% lipid peroxidation inhibition (LPOI) in rat liver homogenate. Antioxidant activity did not show direct correlation with the amount of flavonoid contents in the extracts. However, direct correlation was observed between DPPH free radical scavenging activity and LPOI. Antioxidant activity of the extracts was compared with standard antioxidants. The differential activity observed in extracts could be attributed to the presence of other phytochemicals such as tannins and terpenoids in addition to flavonoids. The study demonstrated appreciable protective efficacy in S. xanthocarpum root extracts against free radical damage.

Estimation of Embelin in Embelia tsjeriam-cottam Fruits by HPLC to Standardize Harvesting Time

Embelin (2,5-dihydroxy-3-undecyl-2,5-cyclohexadiene-1,4-benzoquinone) is a phenolic compound found in the fruits of Embelia tsjeriam-cottam and is responsible for the medicinal properties of the plant Thus the fruits are harvested at a large scale before maturity leading to depletion of population. Since the chemical constituents of medicinal plants are directly associated with the harvesting time, a study was conducted in different forest areas of Chhattisgarh, India, to standardize the harvesting time of Baividang fruits on the basis of their embelin content during 2005-08. The embelin content was determined by RP-HPLC and varied from 1.09 to 5.21% (w/w). The immature fruits collected in October contain an average of 1.67% embelin whereas mature fruits collected in December on an average contain 4.64% embelin. On the basis of our findings it can be concluded that fruits should be harvested after attaining maturity to get better quality produce and also to maintain the sustainability of plant.

A case of double right coronary artery with bifurcation stenosis in association with complete heart block

Congenital coronary artery anomalies are present at birth, but most anomalies are discovered as incidental findings during coronary angiography or at autopsy. Double right coronary artery (RCA) is a rare coronary anomaly. Double RCA with bifurcation stenosis in association with degenerative complete heart block (CHB) have never been reported in literature to the best of our knowledge. We therefore report an interesting case of a patient with double RCA and degenerative CHB.

Psychiatric symptomatology, scholastics, and phenytoin

Phenytoin is a commonly used antiepileptic medication because of its easy accessibility as well as affordability. However, scientific literature shows various types of side effects of phenytoin. We report a patient who was showing toxicity symptoms in the form of mood, behavior and cognitive symptoms along with scholastic problems and personality change on long term treatment with phenytoin. The patient's serum phenytoin was found to be quite high (>32.8 ng/ml).The symptoms were attributed to phenytoin toxicity which responded within twelve weeks by reducing the dose of phenytoin (with resultant fall in levels of serum phenytoin) and the addition of folic acid. While the mood and behavior symptoms recovered early, the cognitive symptoms responded slowly showing 80% -90 % improvement over a period of fifteen weeks.

Physiological effects of arsenate on transplant thalli of the lichen Pyxine cocoes (Sw.) Nyl

INTRODUCTION

The changes in photosynthetic pigments, chlorophyll fluorescence, protein content, and antioxidant enzymes were investigated in a foliose lichen Pyxine cocoes, which was subjected to increasing concentrations of arsenate.

METHODS

The arsenate concentrations of 10, 25, 50, 75, 100, and 200 μM were sprayed every alternate day on the lichen thallus. The thalli were then harvested on 10, 20, 30, and 45 days.

RESULTS

The quantity of photosynthetic pigments exhibited a decreasing trend till 20 days but increased from 30 days onwards. Concomitantly, chlorophyll fluorescence also showed a decreasing trend with increasing arsenic treatment duration as well as concentration. The higher concentration of arsenate was found to be deleterious to the photosynthesis of lichen as the chlorophyll fluorescence and the amount of pigments decreased significantly. The protein content of lichen increased uninterruptedly as the concentration of arsenate as well as duration of treatment increased. The activities of superoxide dismutase and ascorbate peroxide increased initially at lower concentration of arsenate but declined at higher concentrations and longer duration of treatment.

CONCLUSIONS

The catalase activity was found to be most susceptible to arsenate stress as its activity started declining from very beginning of the experiment. P. cocoes also proved to be an excellent accumulator of arsenate whose concentration increased in the thallus corresponding to its increase in the treatment and duration. Thus, it can be utilized for active biomonitoring of arsenic pollution.

Differentiation of four Indian aboriginal cattle populations revealed by STR markers

Cattle are the most important livestock in India and play a pivotal role in agrarian economy. There are 34 recognized breeds of cattle and number of unexplored lesser known populations. The present study is a contribution towards determining genetic variation and understanding the relationship among four lesser known populations. A total of 194 unrelated DNA samples from three cattle populations of Orissa (Binjharpuri, Ghumsuri, Motu) and Hill cattle of Kumaun (Kumauni) were collected from respective breeding tracts. Genotyping was done with 23 bovine microsatellite markers as suggested by International Society for Animal Genetics (ISAG) and FAO (DAD-IS) on automated sequencer. The average observed heterozygosity in the four populations lie within the narrow range of 0.623 +/- 0.04 in Binjharpuri to 0.664 +/- 0.03 in Kumauni. Mean estimates of observed and expected heterozygosity over all loci and breeds were 0.651 +/- 0.02 and 0.720 +/- 0.01, respectively. In the overall population, the homozygote excess (F(IT)) of 0.132 +/- 0.03, was partly due to the genetic differentiation among breeds (F(ST) = 0.044 +/- 0.01) and, to a larger extent, to a significant homozygote excess within breeds (F(IS) = 0.094 +/- 0.03). The phylogenetic reconstruction from a UPGMA clustering based on Nei's Standard genetic distance yielded a tree with Binjharpuri and Ghumsuri on a single node and Motu and Kumauni on separate nodes. The most probable clustering detected by STRUCTURE in population was three. Binjharpuri and Ghumsuri animals were assigned to one cluster with high proportion of membership.

Clinico-demographic profile, sexual dysfunction and readiness to change in male alcohol dependence syndrome inpatients in a tertiary hospital

Persons with prolonged and heavy alcohol use generally suffer from alcohol dependence syndrome (ADS) and develop physical, sexual as well as psychiatric co-morbidity. Successful recovery to normalcy depends on multiple factors including patient's motivation. To study clinico-demographic profile, reasons for initiating alcohol use, sexual and psychiatric disorders and eagerness for treatment and quitting alcohol in ADS inpatients. Fifty consecutive ADS inpatients with matching controls were enrolled. Clinico-demographic profile, factors for initiating alcohol use, psychiatric and sexual co-morbidity and want for treatment and being abstinent was studied applying relevant scales. All subjects were males with a mean age of 37.5 years, 80% were married, majority were Hindu (88%) and from nuclear families (56%). Fifty two percent had an education level of Graduation or more and 68% of patients reported peer pressure to be the initiating factor for alcohol use. Seventy six percent had psychiatric co-morbidity including personality Problems and other Psychiatric disorders 19(38%), delirium tremens 14 (28.00%) and Mood disorders 12(24%).Depression being most common mood disorder (14%). Nicotine was the most common other substance of use 32 (64%). Sixty eight percent of the patient reported one or another sexual dysfunction. 68% of ADS inpatients acknowledged of having problems related to their drinking, expressed desire for change and were eager to avail treatment and to remain abstinent. ADS patients commonly suffer from psychiatric co-morbidity and sexual dysfunctions. They also wish to have effective treatment and to quit alcohol.

Neurocognitive deficits in male alcoholics: an ERP/sLORETA analysis of the N2 component in an equal probability Go/NoGo task

In alcoholism research, studies concerning time-locked electrophysiological aspects of response inhibition have concentrated mainly on the P3 component of the event-related potential (ERP). The objective of the present study was to investigate the N2 component of the ERP to elucidate possible brain dysfunction related to the motor response and its inhibition using a Go/NoGo task in alcoholics. The sample consisted of 78 abstinent alcoholic males and 58 healthy male controls. The N2 peak was compared across group and task conditions. Alcoholics showed significantly reduced N2 peak amplitudes compared to normal controls for Go as well as NoGo task conditions. Control subjects showed significantly larger NoGo than Go N2 amplitudes at frontal regions, whereas alcoholics did not show any differences between task conditions at frontal regions. Standardized low resolution electromagnetic tomography analysis (sLORETA) indicated that alcoholics had significantly lower current density at the source than control subjects for the NoGo condition at bilateral anterior prefrontal regions, whereas the differences between groups during the Go trials were not statistically significant. Furthermore, NoGo current density across both groups revealed significantly more activation in bilateral anterior cingulate cortical (ACC) areas, with the maximum activation in the right cingulate regions. However, the magnitude of this difference was much less in alcoholics compared to control subjects. These findings suggest that alcoholics may have deficits in effortful processing during the motor response and its inhibition, suggestive of possible frontal lobe dysfunction.

Type IV Dual Left Anterior Descending Coronary Artery:A Rare Anomaly

Type IV dual left anterior descending (LAD) coronary artery is a rare anomaly and was detected incidentally during a routine coronary angiogram. The article discusses the types of dual LAD and their clinical implications.
