ABSTRACT

Cocoa products namely cocoa powder (CP), cocoa butter (CB) and cocoa mass (CM) were selected for their utilization in soft dough biscuits. CP was blended with the refined wheat flour (WF-0, 5, 10 and 15% levels) and rheological and quality characteristics of biscuits were studied. The spread ratio decreased (10.1-8.8), density (0.49-0.52 g/cm3) and breaking strength values (1127-1369 g force) increased gradually with increase in CP. Combination of GMS and SSL at 0.25% each improved the quality of biscuits at 10% incorporation of CP. Further the biscuit fat (BF) was replaced with CB (0, 25, 50 and 75%). Later the biscuits with CM were prepared by replacing the flour (15%) and BF (0, 25, 50 and 75%). Acceptability of the CM based biscuits was better when compared to CB based biscuits. The total polyphenol content in control biscuits was 55.55 mg/100 g and was in the range between 81.98 and 102.05 mg/100 g for cocoa based biscuits. The protein content in cocoa based biscuits was marginally higher than the control biscuit. Though there was a wide variation in the fat content and different fatty acids in raw materials, interestingly, the values varied narrowly in biscuits.

ABSTRACT

Haplotype-based breeding (HBB) is one of the cutting-edge technologies in the realm of crop improvement due to the increasing availability of Single Nucleotide Polymorphisms identified by Next Generation Sequencing technologies. The complexity of the data can be decreased with fewer statistical tests and a lower probability of spurious associations by combining thousands of SNPs into a few hundred haplotype blocks. The presence of strong genomic regions in breeding lines of most crop species facilitates the use of haplotypes to improve the efficiency of genomic and marker-assisted selection. Haplotype-based breeding as a Genomic Assisted Breeding (GAB) approach harnesses the genome sequence data to pinpoint the allelic variation used to hasten the breeding cycle and circumvent the challenges associated with linkage drag. This review article demonstrates ways to identify candidate genes, superior haplotype identification, haplo-pheno analysis, and haplotype-based marker-assisted selection. The crop improvement strategies that utilize superior haplotypes will hasten the breeding progress to safeguard global food security.

ABSTRACT

ABSTRACT: Staphylococcal scalded skin syndrome (SSSS), also known as Ritter's disease, in its severe form occurs predominantly in infants and children. It is caused by infection with group II (often phage group 71) Staphylococcus aureus. The foci of infection include nasopharynx, less commonly umbilicus, urinary tract, superficial abrasion, conjunctivae, and blood. Staphylococci are non-motile, non-spore-forming, catalase-positive, gram-positive cocci that appear predominantly as grape-like clusters. Although this organism is frequently a part of normal human microbial flora, it can cause significant opportunistic infections under certain conditions such as when extremes of age groups are involved, the presence of indwelling medical devices, and intravenous (iv) drug abuse. Staphylococcus aureus may cause a variety of infectious manifestations ranging from relatively benign skin infections to life-threatening systemic illnesses. SSSS caused by S. aureus strains produces exfoliative toxins which result in the development of blisters, erythema, and desquamation. Here, we present a case of an 11-day-old neonate who was diagnosed with SSSS. The causative agent responsible for this syndrome was identified as methicillin-resistant Staphylococcus aureus (MRSA). The molecular characterization of the gene Panton-Valentine leukocidin (PVL) was done by polymerase chain reaction (PCR) and was detected positive for PVL which is a distinctive virulence factor seen almost in all of the community-acquired MRSA strains. The patient was discharged after parenteral clindamycin therapy with almost complete resolution of symptoms.

ABSTRACT

BACKROUND: Inflammation characterized by the presence of T and B cells is often observed in prostate cancer, but it is unclear how T- and B-cell levels change during carcinogenesis and whether such changes influence disease progression. METHODS: The study used a retrospective sample of 73 prostate cancer cases (45 whites and 28 African Americans) that underwent surgery as their primary treatment and had a benign prostate biopsy at least 1 year before diagnosis. CD3+, CD4+, and CD20+ lymphocytes were quantified by immunohistochemistry in paired pre- and post-diagnostic benign prostate biopsy and tumor surgical specimens, respectively. Clusters of similar trends of expression across two different timepoints and three distinct prostate regions-benign biopsy glands (BBG), tumor-adjacent benign glands (TAG), and malignant tumor glandular (MTG) regions-were identified using Time-series Anytime Density Peaks Clustering (TADPole). A Cox proportional hazards model was used to estimate the hazard ratio (HR) of time to biochemical recurrence associated with region-specific lymphocyte counts and regional trends. RESULTS: The risk of biochemical recurrence was significantly reduced in men with an elevated CD20+ count in TAG (HR = 0.81, p = 0.01) after adjusting for covariates. Four distinct patterns of expression change across the BBG-TAG-MTG regions were identified for each marker. For CD20+, men with low expression in BBG and higher expression in TAG compared to MTG had an adjusted HR of 3.06 (p = 0.03) compared to the reference group that had nominal differences in CD20+ expression across all three regions. The two CD3+ expression patterns that featured lower CD3+ expression in the BBG compared to the TAG and MTG regions had elevated HRs ranging from 3.03 to 4.82 but did not reach statistical significance. CONCLUSIONS: Longitudinal and spatial expression patterns of both CD3+ and CD20+ suggest that increased expression in benign glands during prostate carcinogenesis is associated with an aggressive disease course.

ABSTRACT

Human beings always remained attracted towards vivid food flavours and aroma. Ever since the food industry came into existence, several brands and industries worldwide have been busy creating storms in the food markets through flavours, aromas, textures and substances to intrigue the consumers' minds. The ingredients that go into the preparation of these food items include a list of various preservatives, taste enhancers, stabilizers, colours and to make it look attractive and delicious but may not be healthy. Most of the flavours that are used by food brands are often chemical based and are synthesized completely in the laboratory. The use of artificial/synthetic flavourings in the form of chemical food additives and taste enhancers lead to long term health issues which include potential risks of neurological problems, cytotoxicity, genotoxicity, different types of hypersensitivities and even cancers. Food and Drug Administration (FDA, USA) conduct frequent studies to limit the use of artificial flavouring and additives which are totally chemical based and mimic natural food flavours and extract. Benzaldehyde-an organic chemical closely resembles the flavour of roasted almonds and ethyl vanillin which is 3 times potent than natural vanilla extract used is various confectionery items. Also several ester derivatives are used for mimicking natural fruit flavours like strawberry, guava and cherry. These chemicals pose a considerable threat to human health, knowingly or unknowingly. Antagonistically, natural food flavours, though not as popular as artificial ones prove to be healthier and carry the same aroma and taste as artificial flavouring agents. This review paper sheds light on the pervasiveness of natural and artificial food flavouring agents in the market, their benefits and drawbacks and how they have been in a constant race for dominating the bakery industry.

ABSTRACT

LAY ABSTRACT: Young adults with autism spectrum disorder over 18 years of age are an underserved population, and there is presently limited evidence examining the effects of physical activity programs in this population. Our review synthesizes the evidence to date from studies that have assessed the effects of physical activity/exercise programs in young adults with autism spectrum disorder between 19 and 30 years. We reviewed 22 studies that included a total of 763 young adults with autism spectrum disorder. There is the strongest evidence for improvements in physical fitness, followed by motor skills, psychological function, and quality of life following physical activity interventions in young adults with autism spectrum disorder. Specifically, aerobic and resistance training as well as programs focused on movement skill and sport-specific training lead to improved physical fitness and movement performance. Holistic interventions focusing on physical activity, dietary changes, and lifestyle modifications lead to improvements in body composition and quality of life of young adults with autism spectrum disorder. There is presently limited evidence to support the use of exercise/activity programs to improve physical activity levels and core autism symptoms in young adults with autism spectrum disorder. Based on our review results, we also provide practical recommendations for clinicians working with young adults with autism spectrum disorder.

ABSTRACT

MAIN CONCLUSION: Exogenous application of dsRNA molecules targeting MYMV genes offers a promising approach to effectively mitigate yellow mosaic disease in blackgram, demonstrating potential for sustainable plant viral disease management. The exogenous application of double-stranded RNA (dsRNA) molecules to control plant viral diseases is gaining traction due to its advantages over conventional methods, such as target specificity, non-polluting nature, and absence of residue formation. Furthermore, this approach does not involve genome modification. In this study, dsRNA molecules targeting the coat protein gene (dsCP) and replication initiator protein gene (dsRep) of mungbean yellow mosaic virus (MYMV) were synthesised using an in vitro transcription method. To evaluate the effectiveness of dsRNA treatment, blackgram plants exhibiting MYMV symptoms at the first trifoliate stage were subjected to exogenous application of dsRNA. Second, third, and fourth trifoliate leaves, which emerged at 7, 15, and 21 days after dsRNA application, respectively, were monitored for MYMV symptoms. Remarkably, a significant reduction in yellow mosaic disease (YMD) symptoms was observed in the newly emerged trifoliate leaves of MYMV-infected blackgram plants after treatment with dsRNA targeting both gene regions. This reduction was evident as a decrease in the intensity of yellow mosaic coverage on the leaf lamina compared to control. dsCP effectively reduced the MYMV titre in the treated plants for up to 15 days. However, dsRep demonstrated greater efficiency in conferring resistance to MYMV at 15 days post-application. These findings were supported by quantitative real-time PCR analysis, where the observed Ct values for DNA extracted from dsRep-treated plants were significantly higher compared to the Ct values of DNA from dsCP-treated plants at 15 days post-application. Similarly, higher viral copy numbers were observed in dsCP-treated plants 15 days after dsRNA treatment, in contrast to plants treated with dsRep.

ABSTRACT

Differential classification of prostate cancer grade group (GG) 2 and 3 tumors remains challenging, likely because of the subjective quantification of the percentage of Gleason pattern 4 (%GP4). Artificial intelligence assessment of %GP4 may improve its accuracy and reproducibility and provide information for prognosis prediction. To investigate this potential, a convolutional neural network (CNN) model was trained to objectively identify and quantify Gleason pattern (GP) 3 and 4 areas, estimate %GP4, and assess whether CNN-predicted %GP4 is associated with biochemical recurrence (BCR) risk in intermediate-risk GG 2 and 3 tumors. The study was conducted in a radical prostatectomy cohort (1999-2012) of African American men from the Henry Ford Health System (Detroit, Michigan). A CNN model that could discriminate 4 tissue types (stroma, benign glands, GP3 glands, and GP4 glands) was developed using histopathologic images containing GG 1 (n = 45) and 4 (n = 20) tumor foci. The CNN model was applied to GG 2 (n = 153) and 3 (n = 62) tumors for %GP4 estimation, and Cox proportional hazard modeling was used to assess the association of %GP4 and BCR, accounting for other clinicopathologic features including GG. The CNN model achieved an overall accuracy of 86% in distinguishing the 4 tissue types. Furthermore, CNN-predicted %GP4 was significantly higher in GG 3 than in GG 2 tumors (P = 7.2 × 10-11). %GP4 was associated with an increased risk of BCR (adjusted hazard ratio, 1.09 per 10% increase in %GP4; P = .010) in GG 2 and 3 tumors. Within GG 2 tumors specifically, %GP4 was more strongly associated with BCR (adjusted hazard ratio, 1.12; P = .006). Our findings demonstrate the feasibility of CNN-predicted %GP4 estimation, which is associated with BCR risk. This objective approach could be added to the standard pathologic assessment for patients with GG 2 and 3 tumors and act as a surrogate for specialist genitourinary pathologist evaluation when such consultation is not available.

ABSTRACT

BACKGROUND: Telomere shortening is linked to aging and may be associated with increased risk for cancer. Most cancer studies have used telomere length in leukocytes rather than in the target tissue of cancer origin. METHODS: A case-control study of 524 case-control pairs with a benign prostate biopsy nested within a historical cohort of 10,478 men was conducted to determine whether premalignant prostate telomere length (assessed using a modified qRT-PCR) is associated with prostate cancer risk. RESULTS: Telomere lengths in benign prostate biopsies of cases versus controls were similar (1.46 ± 0.38 vs. 1.45 ± 0.42; P = 0.49). African American (AA) men had significantly shorter telomeres compared with White men (1.51 ± 0.38 vs. 1.63 ± 0.39; P < 0.0001). In race-stratified analyses, increasing telomere length was more strongly associated with prostate cancer risk in White men, wherein those with telomere length in the highest quartile had 1.9-fold greater adjusted risk of prostate cancer compared with men with prostate telomere lengths in the lowest quartile [OR = 1.90; 95% confidence interval (CI) = 1.08-3.36]. Men in the highest telomere length quartile also had a greater risk of aggressive prostate cancer compared with men with telomere lengths in the lowest quartile (OR = 2.78; 95% CI = 1.25-6.19). CONCLUSIONS: White men have longer telomeres in benign prostate tissue compared with AA men, and those with the longest telomeres may be at increased risk for prostate cancer, particularly the more aggressive form of the disease. IMPACT: Race-specific telomere length measures may be an early biomarker of aggressive prostate cancer.

ABSTRACT

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder affecting multiple developmental domains including social communication, behavioral-affective, sensorimotor, and cognitive systems. There is growing evidence for the use of holistic, whole-body, Creative Movement Therapies (CMT) such as music, dance, yoga, theater, and martial arts in addressing the multisystem impairments in ASD. We conducted a comprehensive quantitative and qualitative review of the evidence to date on the effects of CMT on multiple systems in individuals with ASD. The strongest evidence, both in terms of quantity and quality, exists for music and martial arts-based interventions followed by yoga and theater, with very limited research on dance-based approaches. Our review of 72 studies (N = 1,939 participants) across participants with ASD ranging from 3 to 65 years of age suggests that at present there is consistent evidence from high quality studies for small-to-large sized improvements in social communication skills following music and martial arts therapies and medium-to-large improvements in motor and cognitive skills following yoga and martial arts training, with insufficient evidence to date for gains in affective, sensory, and functional participation domains following CMT. Although promising, our review serves as a call for more rigorous high-quality research to assess the multisystem effects of CMT in ASD. Based on the existing literature, we discuss implications of our findings for autism researchers and also provide evidence-based guidelines for clinicians to incorporate CMT approaches in their plan of care for individuals with ASD.

ABSTRACT

Fat and sugar are responsible for the structure of cookies but make them nutritionally inferior. Therefore, in the present study, cookies with improved nutrition using whole wheat flour (WWF) and incorporation of multigrain mix (MM-oats, peas and fenugreek flours) at 0, 25, 50, 75 and 100% levels was studied. Further, fat was replaced using pumpkin seed (PS) or watermelon seed (WS) at 25, 50 and 75% level and sugar was replaced using dry dates (DD) or raisins (RS) separately at 20, 40 and 60%. MM having protein at 15.13% and dietary fibre at 12.83% significantly decreased the water absorption (68.1-60.6%), stability (2.52-1.35 min), amylograph peak viscosity (665-821 BU), and cookie dough hardness (1737-690.5) at 100% MM. Based on the physico-sensory analysis, 75% replacement of WWF with MM was selected for replacement of fat or sugar. Addition of PS or WS increased the dough hardness (1235-4103 g), whereas the spread ratio of cookies decreased from 6.25 and 6.31 to 5.54 and 4.06 respectively. Replacement of fat with PS at 50%, sugar by DD at 40% along with a combination of sodium stearoyl lactylate (SSL) and glycerol mono stearate (GMS) showed improvement in the cookie texture. The scanning electron microscope (SEM) of cookie showed coating of starch granules and appearance of sheet-like covering of protein network. The mono and polyunsaturated fatty acid profile of cookies improved apart from a two-fold increase in protein and three-fold increase in dietary fibre.

ABSTRACT

Systemic inflammation may increase risk for prostate cancer progression, but the role it plays in prostate cancer susceptibility is unknown. From a cohort of over 10,000 men who had either a prostate biopsy or transurethral resection that yielded a benign finding, we analyzed 517 incident prostate cancer cases identified during follow-up and 373 controls with one or more white blood cell tests during a follow-up period between one and 18 years. Multilevel, multivariable longitudinal models were fit to two measures of systemic inflammation, neutrophil-to-lymphocyte ratio (NLR) and monocyte-to-lymphocyte ratio (MLR), to determine NLR and MLR trajectories associated with increased risk for prostate cancer. For both measures, we found no significant differences in the trajectories by case/control status, however in modeling NLR trajectories there was a significant interaction between race (white or Black and case-control status. In race specific models, NLR and MLR values were consistently higher over time among white controls than white cases while case-control differences in NLR and MLR trajectories were not apparent among Black men. When cases were classified as aggressive as compared to non-aggressive, the case-control differences in NLR and MLR values over time among white men were most apparent for non-aggressive cases. For NLR among white men, significant case-control differences were observed for the entire duration of observation for men who had inflammation in their initial prostate specimen. It is possible that, among white men, monitoring of NLR and MLR trajectories after an initial negative biopsy may be useful in monitoring prostate cancer risk.

ABSTRACT

The study aimed to utilize buckwheat and bread waste to develop ready to eat snack with reduced fat, enriched protein, dietary fiber and minerals. Base flour constituting of buckwheat flour (BF) and rice flour in the ratio of 90:10 was replaced with bread powder (BP) at varying levels (0-80%). The gelatinization temperature of base flour was 67 °C and it decreased with increasing amount of BF. The breaking strength of the extruded snack with varying amount of BP, fat and chilli powder were in the range between 3.46-2.04 N, 1.56-1.26 N and 1.5-1.89 N respectively. Physical and sensory analyses indicate that 40% BP, 8% fat and 1% chilli powder were optimum to obtain extruded snack with desirable characteristics. The ready to eat snack contained 10.64%, 15.33% and 7.45% of fat, protein and total dietary fiber respectively. Minerals present were 169 mg/100 g of magnesium, 46 mg/100 g of calcium, 4.5 mg/100 g of iron and 3.46 mg/100 g of zinc. Bread waste can thus be utilized in producing a healthy ready to eat snack.

ABSTRACT

Growth and differentiation factor 15 (GDF-15), also known as macrophage inhibitory cytokine 1 (MIC-1), may act as both a tumor suppressor and promotor and, by regulating NF-κB and macrophage signaling, promote early prostate carcinogenesis. To determine whether expression of these two inflammation-related proteins affect prostate cancer susceptibility, dual immunostaining of benign prostate biopsies for GDF-15 and NF-κB was done in a study of 503 case-control pairs matched on date, age, and race, nested within a historical cohort of 10,478 men. GDF-15 and NF-κB expression levels were positively correlated (r = 0.39; p < 0.0001), and both were significantly lower in African American (AA) compared with White men. In adjusted models that included both markers, the odds ratio (OR) for NF-κB expression was statistically significant, OR =0.87; p = 0.03; 95% confidence interval (CI) =0.77-0.99, while GDF-15 expression was associated with a nominally increased risk, OR =1.06; p = 0.27; 95% CI =0.96-1.17. When modeling expression levels by quartiles, the highest quartile of NF-κB expression was associated with almost a fifty percent reduction in prostate cancer risk (OR =0.51; p = 0.03; 95% CI =0.29-0.92). In stratified models, NF-κB had the strongest negative association with prostate cancer in non-aggressive cases (p = 0.03), older men (p = 0.03), and in case-control pairs with longer follow-up (p = 0.02). Risk associated with GDF-15 expression was best fit using nonlinear regression modeling where both first (p = 0.02) and second (p = 0.03) order GDF-15 risk terms were associated with significantly increased risk. This modeling approach also revealed significantly increased risk associated with GDF-15 expression for subsamples defined by AA race, aggressive disease, younger age, and in case-control pairs with longer follow-up. Therefore, although positively correlated in benign prostatic biopsies, NF-κB and GDF-15 expression appear to exert opposite effects on risk of prostate tumor development.

ABSTRACT

BACKGROUND: Pan-cancer studies of somatic copy number alterations (SCNAs) have demonstrated common SCNA patterns across cancer types, but despite demonstrable differences in aggressiveness of some cancers by race, pan-cancer SCNA variation by race has not been explored. This study investigated a) racial differences in SCNAs in both breast and prostate cancer, b) the degree to which they are shared across cancers, and c) the impact of these shared, race-differentiated SCNAs on cancer survival. METHODS: Utilizing data from The Cancer Genome Atlas (TCGA), SCNAs were identified using GISTIC 2.0, and in each tumor type, differences in SCNA magnitude between African Americans (AA) and European Americans (EA) were tested using linear regression. Unsupervised hierarchical clustering of the copy number of genes residing in race-differentiated SCNAs shared between tumor types was used to identify SCNA-defined patient groups, and Cox proportional hazards regression was used to test for association between those groups and overall/progression-free survival (PFS). RESULTS: We identified SCNAs that differed by race in breast (n = 58 SCNAs; permutation p < 10- 4) and prostate tumors (n = 78 SCNAs; permutation p = 0.006). Six race-differentiated SCNAs common to breast and prostate found at chromosomes 5q11.2-q14.1, 5q15-q21.1, 8q21.11-q21.13, 8q21.3-q24.3, 11q22.3, and 13q12.3-q21.3 had consistent differences by race across both tumor types, and all six were of higher magnitude in AAs, with the chromosome 8q regions being the only amplifications. Higher magnitude copy number differences in AAs were also identified at two of these race-differentiated SCNAs in two additional hormonally-driven tumor types: endometrial (8q21.3-q24.3 and 13q12.3-q21.3) and ovarian (13q12.3-q21.3) cancers. Race differentiated SCNA-defined patient groups were significantly associated with survival differences in both cancer types, and these groups also differentiated within triple negative breast cancers based on PFS. While the frequency of the SCNA-defined patient groups differed by race, their effects on survival did not. CONCLUSIONS: This study identified race-differentiated SCNAs shared by two related cancers. The association of SCNA-defined patient groups with survival demonstrates the clinical significance of combinations of these race-differentiated genomic aberrations, and the higher frequency of these alterations in AA relative to EA patients may explain racial disparities in risk of aggressive breast and prostate cancer.

ABSTRACT

M2 (tumor-supportive) macrophages may upregulate growth differentiation factor 15 (GDF15), which is highly expressed in prostate tumors, but the combined utility of these markers as prognostic biomarkers are unclear. We retrospectively studied 90 prostate cancer cases that underwent radical prostatectomy as their primary treatment and were followed for biochemical recurrence (BCR). These cases also had a benign prostate biopsy at least 1 year or more before their prostate cancer surgery. Using computer algorithms to analyze digitalized immunohistochemically stained slides, GDF15 expression and the presence of M2 macrophages based on the relative density of CD204- and CD68-positive macrophages were measured in prostate: (i) benign biopsy, (ii) cancer and (iii) tumor-adjacent benign (TAB) tissue. Both M2 macrophages (P = 0.0004) and GDF15 (P < 0.0001) showed significant inter-region expression differences. Based on a Cox proportional hazards model, GDF15 expression was not associated with BCR but, in men where GDF15 expression differences between cancer and TAB were highest, the risk of BCR was significantly reduced (hazard ratio = 0.26; 95% confidence interval = 0.09-0.94). In addition, cases with high levels of M2 macrophages in prostate cancer had almost a 5-fold increased risk of BCR (P = 0.01). Expression of GDF15 in prostate TAB was associated with M2 macrophage levels in both prostate cancer and TAB and appeared to moderate M2-macrophage-associated BCR risk. In summary, the relationship of GDF15 expression and CD204-positive M2 macrophage levels is different in a prostate tumor environment compared with an earlier benign biopsy and, collectively, these markers may predict aggressive disease.

ABSTRACT

AIM: The management of diabetes has become a challenge due to the COVID 19 lockdown. An online-based pilot survey was conducted to study how people with diabetes were coping with their Diabetes during the COVID - 19 lockdown. METHOD: The questions were designed in an online survey, Survey Monkey, to conduct this cross-sectional study. The link was generated and sent to 100 registered patients of the MV Hospital for Diabetes Royapuram who had not contacted the hospital after the lockdown announcement. The survey was done between April 1 and April 15, 2020.Oral consent was obtained through telephone before the link was sent by Whatsapp to them.The questionnaire consisted of questions on home blood glucose monitoring, regularity in doing their physical activity and dietary compliance and anxiety about the viral infection. RESULTS: 92% of the participants had Type 2 diabetes. Only 28% of the participants were checking their blood glucose levels regularly. 80% of the participants mentioned that they were following regular exercise and diet control during the lockdown period. 40% of the participants were anxious about the Covid infection. CONCLUSION: SMBG needs to be practiced on regular basis, especially among the patients with diabetes on insulin therapy. Most of the people surveyed were coping well with their Diabetes. Patients have reported that they were able to maintain proper dietary compliance and be more physically active at home during this lockdown. These findings need to be ascertained in larger sample of patients.

ABSTRACT

BACKGROUND: Probiotic organisms are known to reduce caries causing microorganisms mutans streptococci and lactobacilli. Aim of the Study. To evaluate the effect of probiotic Bacillus coagulans Unique IS2 on mutans streptococci and lactobacilli levels in saliva and plaque in children. INTRODUCTION: Dental caries or tooth decay is because of the demineralization of the tooth enamel leading to the breakdown of the enamel causing cavities to be formed. Demineralization of the tooth happens because of the acid secreted by bacteria like mutans streptococci and lactobacilli. It is now suggested that probiotic usage prevents the overgrowth of these pathogenic microbes, thereby reducing caries activity. Methodology. In this double-blind, randomized, placebo-controlled study, 48 children with ages ranging from 5 to 15 years were divided into two groups, the probiotic and placebo groups. Chewable tablets with and without probiotic Bacillus coagulans Unique IS2 were administered for two weeks. Stimulated saliva samples and plaque were collected at baseline and at the end of 14 days to measure the pH, mutans streptococci, and lactobacilli count of saliva and plaque using chairside kits. RESULTS: A statistically significant reduction in mutans streptococci and lactobacilli counts of both saliva and plaque samples was observed in the B. coagulans Unique IS2 treated group after 14 days of administration compared to the baseline and placebo group (using paired t-test). CONCLUSION: Probiotic Bacillus coagulans Unique IS2 (2 billion cfu) chewable tablet is effective in reduction and inhibition of caries causing mutans streptococci and lactobacilli levels in saliva and plaque in children.
