ABSTRACT

The human milk fat globule membrane (hMFGM) and Lactobacillus modulate the infant's gut and benefit health. Hence, the current study assesses the probiotic potential of Lactiplantibacillus plantarum (MRK3), Limosilactobacillus ferementum (MK1) isolated from infant feces, and its interaction with hMFGM during conditions mimicking infant digestive tract. Both strains showed high tolerance to gastrointestinal conditions, cell surface hydrophobicity, and strong anti-pathogen activity against Staphylococcus aureus. During digestion, hMFGM significantly exhibited xanthine oxidase activity, membrane roughness, and surface topography. In the presence of hMFGM, survival of MRK3 was higher than MK1, and electron microscopic observation revealed successful entrapment of MRK3 in the membrane matrix throughout digestion. Interestingly, probiotic-membrane matrix interaction showed significant synergy to alleviate oxidative stress and damage induced by cell-free supernatant of Escherichia coli in Caco-2 cells. Our results show that a probiotic-encapsulated membrane matrix potentially opens the functional infant formula development pathway.

ABSTRACT

Human milk, the gold standard for optimal nourishment, controls the microbial composition of infants by either enhancing or limiting bacterial growth. The milk fat globule membrane has gained interest in gut-related functions and cognitive development. The membrane proteins can directly interact with probiotic bacteria, influencing their survival and adhesion through gastrointestinal transit, whereas membrane phospholipids increase the residence time of probiotic bacteria in the gut. The commensal bacteria in milk act as the initial inoculum in building up the gut colonization of an infant, whereas oligosaccharides promote proliferation of beneficial microorganisms. Interestingly, milk extracellular vesicles are also involved in influencing the microbiota composition but are not well-explored. This review highlights the contribution of different milk components in modulating the infant gut microbiota, particularly the fat globule membrane, and the complex interplay between host- and brain-gut microbiota signaling affecting infant and adult health positively.

ABSTRACT

Plasmacytoma is a neoplastic proliferation of monoclonal plasma cells, which can present clinically as solitary bone neoplasm, extramedullary plasmacytoma, and multiple myeloma. The biological behavior of these tumors is variable from periods of clinical latency to rapid growth and progression from localized forms to more disseminated multiple myeloma. We present the case of solitary plasmacytoma of the mandible with rare bilateral involvement in a 65-year-old female patient. This paper highlights the importance of understanding the maxillofacial manifestations of the disease by the dentist for early diagnosis and thus better prognosis.

ABSTRACT

Hanging drop (HD) three-dimensional (3D) culture model for buffalo granulosa cells (GC) was reported to mimic the preovulatory stage of ovarian follicles in our previous study. To further verify its reliability, the present study attempted a comparative transcriptome profile of buffalo GC freshly isolated from ovarian follicles (<8 mm diameter) (FC) and their cultures in normal culture dish (ND or 2D), polyHEMA coated dish (PH) and HD culture systems (3D). Out of 223 significantly (-log2 fold change: >3; p < .0005; false discovery rate [FDR]: <0.1) differentially expressed genes (SDEGs) among different culture systems, 137 were found unannotated, and 94, 29, and 66 were exclusively expressed in FC, PH, and HD, respectively. However, on eliminating the fixed points of p values and FDR from the entire raw data, only 11 genes related to long noncoding RNA, 12 genes related to luteinization, and 3 genes related to follicular maturation were exclusively expressed in FC, PH, and HD culture systems, respectively. The quantitative real time-PCR validation and the next generation sequencing data had more than 90% correlation. Bioinformatics analyses of the exclusively expressed SDEG revealed that the freshly aspirated GCs were a true representative of GCs from small follicles (<8 mm diameter), the GC spheroids under PH maintained mitochondrial function, and those cultured in HD system for 6 days simulated the inflammatory milieu required for ovulation. Therefore, the comparative transcriptome profile also reinforced that HD culture system is better in vitro culture method than the other methods analyzed in this study for buffalo GC.

ABSTRACT

Granulosa cell (GC) culture models mimicking the intrafollicular environment are limited. Such models have a great potential in reproductive toxicity studies. The buffalo, a monovulatory species like humans, could be a better model than polyovulatory rodents. Therefore, we targeted the development and characterization of three-dimensional (3D) culture systems for buffalo GCs. The GCs from small ovarian follicles (SF) maintained the CYP19 gene expression for 144 hr in a 2D culture system. Hence, GCs from SF were cultured directly in 3D using hanging drop and Poly-([2-hydroxyethyl methacrylate]) (polyHEMA) methods in the DMEM media containing 1 ng/ml FSH and 10 ng/ml IGF-1 for 144 hr. The expression profile of nine GC-specific transcripts; CYP19, TNFAIP6, AMH, PTI, NR4A1, FSHR, RUNX, LHR, and COX2/PTGS2; revealed that 3D-spheroids developed in hanging drop method maintained the GC phenotype of preovulatory follicles. Therefore, hanging drop method is a best method for culturing GCs to mimic the intrafollicular environment.

ABSTRACT

Robinow's syndrome is a very rare genetic disorder which bears a resemblance to a foetal face. It is characterized by short-limbed dwarfism, defects in vertebral segmentation and abnormalities in the head, face and external genitalia. It has a genetic heterogeneity with autosomal dominant and recessive forms which relates to the severity of phenotype presentation. A rare case of an autosomal recessive form of Robinow's syndrome is presented with emphasis on, characteristic craniofacial and intraoral manifestations to aid in diagnosis and dental management of this patient.

ABSTRACT

Adenoid cystic carcinoma (ACC) of salivary glands is a slow-growing malignant tumor, characterized by wide local infiltration, perineural spread, a propensity to local recurrence and late distant metastasis. Although ACC is the second most common malignant salivary gland neoplasm and constitutes approximately one-third of all salivary gland malignancies, it is relatively rare in parotid gland. Here, we present a case report of a cribriform type of ACC involving parotid salivary gland in a 66-year-old female.

ABSTRACT

Familial progressive hyperpigmentation (FPH) is a rare genodermatosis characterized by hyperpigmented patches in the skin and mucous membranes, present in early infancy, and increase in size and number with age. The genetic basis for FPH remains unknown. We report an unusual case of familial progressive hypermelanosis in a 17-year-old male patient with family history, who presented with a peculiar progressive oral pigmentation disorder. Diagnosis was confirmed by a series of hematological, biochemical, and histopathological investigations. Our paper stresses the need for the dentist to be aware of the systemic conditions that can also manifest in the oral cavity.

ABSTRACT

Odontomas have been extensively reported in the dental literature, and the term refers to tumors of odontogenic origin. Though the exact etiology is still unknown, the postulated causes include: local trauma, infection, inheritance and genetic mutation. The majority of the lesions are asymptomatic; however, may be accompanied with pain and swelling as secondary complaints in some cases. Here, we report a case of a compound odontome in a 14 year old patient.

ABSTRACT

PURPOSE: Morphological dental anomalies of the maxillary lateral incisors are relatively common. However, their simultaneous occurrence is a relatively rare event. We report a case of dens invaginatus and talon cusp concurrently affecting maxillary lateral incisors. The etiology, pathophysiology, association with other dental anomalies, as well as various treatment modalities of these anomalies are discussed. CASE DESCRIPTION: An 18-year-old male patient reported with a complaint of crowding of maxillary front teeth. On intraoral examination, permanent dentition with Class I malocclusion with anterior crowding was observed. Tooth 12 showed a radiopaque invagination from a lingual pit but confined to the crown of the tooth. This invagination was approximately circular with a central core of radiolucency, which was consistent with the diagnosis of a dens invaginatus type I. Tooth 22 showed the talon cusp as a typical inverted cone with enamel and dentine layers and a pulp horn extending only into the base of the cusp. Talon cusp was treated by prophylactic enameloplasty to avoid plaque accumulation, the deep lingual pit was sealed using composite resin and regular clinical and radiographic follow-up was advised. Patient was scheduled for orthodontic treatment to correct crowding of maxillary anterior teeth. CONCLUSION: We emphasize the fact that detailed clinical and radiographic examination of the maxillary lateral incisors is vital in avoiding complications.


OBJETIVO: Anomalias morfológicas dentárias dos incisivos laterais superiores são relativamente comuns. No entanto, a sua ocorrência simultânea é um evento relativamente raro. Relatamos um caso de dens invaginatus e cúspide talon simultaneamente afetando incisivos laterais superiores. A etiologia, fisiopatologia, associação com outras anomalias dentárias, bem como várias modalidades de tratamento destas anomalias são discutidas. DESCRIÇÃO DO CASO: Um paciente de 18 anos, sexo masculino, relatou com queixa de apinhamento dos dentes anteriores superiores. Ao exame intraoral observou-se dentição permanente com má oclusão Classe I com apinhamento anterior. O dente 12 mostrou uma invaginação radiopaca lingual, confinada à coroa do dente. Esta invaginação era aproximadamente circular, com um núcleo central de radioluscência, que foi compatível com o diagnóstico de dens invaginatus tipo I. O dente 22 apresentou uma cúspide talon como um cone invertido típico com esmalte e dentina em camadas. A cúspide talon foi tratada por ameloplastia profilática para evitar acúmulo de placa, a fissura lingual foi selada com resina composta e foram aconselhados controles clínicos e radiográficos. O paciente foi encaminhado para tratamento ortodôntico para corrigir o apinhamento dos dentes anteriores superiores. CONCLUSÃO: Enfatizamos o fato de que o exame clínico e radiográfico detalhado dos incisivos laterais superiores é vital para evitar complicações.

ABSTRACT

PURPOSE: The Sturge-Weber syndrome (SWS) is a rare congenital disorder that occurs sporadically and features lesions of both skin and nervous system. We report a case of 7 year-old girl with Sturge-Weber syndrome and discuss its clinicopathological features, differential diagnosis and also emphasize the importance of its diagnosis in the clinical oral practice. CASE DESCRIPTION: The classic pathognomonic manifestations include angioma of the leptomeninges extending to cerebral cortex with ipsilateral angiomatous lesions, unilateral facial nevus affecting a division of trigeminal nerve, hemiparesis, intracranial calcification, mental retardation and refractory epilepsy. The most apparent indication of SWS is a facial birthmark or "Port Wine Stain" present at birth and typically involving at least one upper eyelid and the forehead. Management of a patient with Sturge-Weber Syndrome may be challenging due to risk of hemorrhage. CONCLUSION: The dentists should focus on comprehensive therapy, starting with behavior management and stress on preventive measures.


OBJETIVO: A síndrome de Sturge-Weber (SWS) é uma rara doença congênita que ocorre esporadicamente e apresenta lesões de pele e do sistema nervoso. Este artigo é um relato de caso de uma menina de 7 anos com SWS para discutir suas características clinicopatológicas, diagnóstico diferencial e enfatizar a importância do seu diagnóstico na prática clínica odontológica. DESCRIÇÃO DO CASO: As manifestações clássicas patognomônicas incluem angioma das leptomeninges que se estendem para o córtex cerebral com lesões angiomatosas ipsilaterais, nevo facial unilateral, que afetam uma divisão do nervo trigêmeo, hemiparesia, calcificação intracraniana, retardo mental e epilepsia refratária. A indicação mais evidente de SWS é uma marca de nascença facial ou "mancha vinho do porto" presente no nascimento e tipicamente envolvendo pelo menos uma pálpebra superior e a testa. O controle clínico de um paciente com SWS pode ser desafiador devido ao risco de hemorragia. CONCLUSÃO: Os dentistas devem adotar uma abordagem terapêutica abrangente, começando com o controle de comportamento e de estresse com medidas preventivas.

ABSTRACT

PURPOSE: To determine optic disc size and its associations in an adult population in central India. METHODS: The Central India Eye and Medical Study (CIEMS), Part 1 is a population-based, cross-sectional cohort study and included 1000 subjects out of 1314 (76.1%) subjects from a rural area of Maharasthra/India, aged 30+ years, invited to participate. Confocal laser scanning tomographic optic disc images were morphometrically examined. RESULTS: Mean optic disc area (2.25 +/- 0.51 mm2, range 1.12-4.61 mm2) was significantly correlated with myopic refractive error (p < 0.001) and axial length (p < 0.001), whereas gender (p = 0.14), body height (p = 0.44) and best corrected visual acuity (p = 0.59) were not significantly associated in multiple regression analysis. CONCLUSIONS: Mean optic disc area is larger in the central Indian population than in White people. Axial length and myopic refractive error are independent factors that influence optic disc size.
