Abstract VG, 25-year-old male, presented with c/c of forwardly placed lower jaw and history of unsatisfactory previous orthodontic treatment. Extraorally, the patient had asymmetrical face and concave profile, competent lips, positive lip step, and chin deviated toward left side by 2 mm. Intraorally, the patient had Angle’s class III type 3 malocclusion with an overjet of (–1) mm, overbite of 0%, and cross-bite wrt 12, 21. The patient was skeletal class III due to macrognathic and prognathic mandible with hypodivergent growth pattern, and proclined upper and retroclined lower incisors. The patient was managed orthosurgically with bimaxillary surgery (maxillary advancement 3 mm + mandibular setback 7 mm) after presurgical decompensation. The case report discusses in detail the diagnosis and comprehensive management of the skeletal class III case.

Primary intestinal lymphangiectasia (PIL) is a rare cause of lymphatic dysfunction leading to enteric protein loss in children. This case report describes a male child, with familial short stature who presented with chronic diarrhoea, anaemia, anasarca, lymphopaenia and hypoalbuminaemia due to PIL. Diagnosis was confirmed through a combination of endoscopic findings and histopathological analysis of small bowel biopsies showing dilated lymphatic vessels in the duodenum. The child responded to dietary intervention with medium chain triglycerides, fat soluble vitamin supplementations and subcutaneous octreotide therapy. The mainstay of management involves nutritional interventions with consideration of other supportive and therapeutic interventions.

In the present work, we investigated the role of cellulose beads as additive for tuning of shear thickening (ST) behavior of traditional colloidal silica-based shear thickening fluids (STFs). STFs were synthesized with colloidal silica in liquid polyethylene glycol (PEG-200). The ST behavior of cellulose-based STF was compared with silica-based STF in terms of the steady-state and dynamic rheological studies while keeping the same total mass loading in PEG-200 polymer matrix. The ST behavior of cellulose-based STF was found to be more than three times higher than the silica-based STF at the same concentration. It can be expected that the cellulose beads with dense surface hydroxyl groups are a prime reason for improved interfacial interaction between the liquid PEG chains and the PEG-coated silica nanoparticles through strong hydrogen bonding. Both the steady-state and dynamic rheological analyses confirmed the better shear thickening and strain thickening behavior, respectively, as well as higher energy absorption property for cellulose-based STFs. The improved ST behavior of porous cellulose-based STF is definitely due to the cluster formation. This has been justifiably complemented by SEM and in situ rheological microscopy analyses.

Aim: To quantify and compare the metal ions released from different bracket-wire combinations and to assess their cytotoxicity. Materials and Methods: A total of 360 fabricated sectional fixed orthodontic appliances were divided into 6 groups. The first three groups consisted of stainless-steel brackets with stainless-steel, snickel-titanium (NiTi), and titanium-molybdenum alloy (TMA) archwires, and the other three groups were fabricated using ceramic brackets (polycrystalline alumina) with stainless-steel, NiTi, and TMA archwires. These appliances were immersed in artificial saliva (pH 6.5 ± 0.5, 37°C), for 1 week, 2 weeks, and 1 month. The nickel and chromium ions released in the artificial saliva were quantified using a flame atomic absorption spectrometer, and cytotoxicity assessment was performed using a 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide (MTT) assay on human cervical cancer cell line. Results: The stainless-steel bracket groups displayed a significantly greater release of nickel and chromium ions compared to the ceramic bracket groups (P < 0.05). However, no significant differences were identified when comparing the three archwire types within the stainless-steel/ceramic bracket groups. At the end of 1 month, the % cell viability demonstrated by the appliances was in the decreasing order of stainless-steel-TMA > ceramic-stainless steel > stainless-steel-NiTi > ceramic-NiTi > stainless-steel-stainless steel > ceramic-TMA. Conclusion: Considerably greater release of nickel and chromium ions was observed from the appliances utilizing stainless-steel brackets compared to those employing ceramic brackets. However, no remarkable difference in the levels of nickel and chromium ions was observed when comparing the three archwires: stainless steel, NiTi, and TMA. In the cytotoxicity assessment, the ceramic-TMA combination displayed the highest level of cytotoxicity, while the stainless-steel-TMA combination displayed the least cytotoxicity.

We explore the realm of uncertainty theory by investigating diverse notions of convergence and statistical convergence concerning complex uncertain sequences. Complex uncertain variables can be described as measurable functions mapping from an uncertainty space to the set of complex numbers. They are employed to represent and model complex uncertain quantities. We introduce the concept of lacunary almost statistical convergence of order α(0<α≤1) for complex uncertain sequences, examining various aspects of uncertainty such as distribution, mean, measure, uniformly almost sure convergence and almost sure convergence. Additionally, we establish connections between the constructed sequence spaces by providing illustrative instances. Importantly, lacunary almost statistical convergence provides a flexible framework for handling sequences with irregular behavior, which often arise in uncertain environments with imprecise data. This makes our approach particularly useful in practical fields such as engineering, data modeling and decision-making, where traditional deterministic methods are not always applicable. Our approach offers a more flexible and realistic framework for approximating functions in uncertain environments where classical convergence may not apply. Thus, this study contributes to approximation theory by extending its tools to settings involving imprecise or noisy data.

Objective: To assess the self-esteem and quality of life (QOL) in patients with complete unilateral cleft lip and palate (UCLP) who were undergoing orthodontic treatment. Materials and Methods: This cross-sectional study was conducted on a total sample of 300 individuals consisted of 150 patients with UCLP (Group I) and 150 normal controls (Group II) with an age range of 10-25 years, who were undergoing comprehensive orthodontic treatment from December 2016 to December 2018. The Self Esteem and QOL were assessed using the Rosenberg Self Esteem scale (RSE) and Modified Paediatric QOL Inventory Scale (M-PQOL), respectively, in Group I and II. Results: The comparison of overall mean scores of responses to RSE questionnaires showed nonsignificant differences for all the responses and was significant only for RSE 6 and RSE 8 in the age group of 10-15 years and 21-25 years, respectively, and nonsignificant for all other questions in all the age groups. The comparison of overall mean scores of M-PQOL for the total sample showed nonsignificant differences in Group I and II for physical functioning, emotional functioning, and school functioning domain, and were highly significant differences (P ≤ 0.001) in the social functioning domain and M-PQOL 12 and M-PQOL 21. Conclusions: This study demands a definite need of a psychologist/psychiatrist among the cleft care team to counsel the patients with cleft during orthodontic treatment for motivating them to gain self-respect and acceptance in the society as certain aspects, particularly social functioning domain made them feel different from normal children because of the functional and aesthetic problems.

People with Advanced HIV Disease (AHD) are at higher risk of TB coinfection and mortality. However, there are challenges in TB diagnosis with the currently recommended diagnostic tools. WHO recommends lateral flow urine lipoarabinomannan (LF-LAM) assay to assist TB diagnosis among AHD patients. We assessed the utility and acceptability of using urine LF-LAM assay for TB diagnosis among patients at public Antiretroviral Therapy (ART) Centres in Mumbai. The cross-sectional study was conducted among adult AHD patients accessing care from 17 ART centres during November,2020-June, 2021. Urine LF-LAM was offered as routine care for eligible patients in combination with standard diagnostic tests. We calculated the proportion of positive LF-LAM results by CD4 categories and TB symptoms and performed multivariable logistic regression to determine the factors associated with LF-LAM positivity. Among 2,390 patients, the majority (74.5%) had CD4 between 101-200 cells/mm.sup.3 . The mean age was 43.7 years (SD:10.6), 68.6% were male, 8.4% had TB symptoms and 88.0% were on ART. The overall proportion of patients with urine LF-LAM positive results was 6.4%. Among PLHIV with CD4[less than or equal to]100 cells/mm.sup.3, the positivity was 43.0% and 7.7% in symptomatic and asymptomatic patients, respectively. Among PLHIV with a CD4>100 cells/mm.sup.3, the positivity was 26.7% and 2.7% in symptomatic and asymptomatic patients respectively. Urine LF-LAM positivity was higher among inpatients, ART naïve, patients on treatment for <6 months, symptomatic and in WHO clinical stage III/IV of HIV disease as compared to the reference categories. We detected an additional 131 TB cases with urine LF-LAM in combination with the standard diagnostic tests. The study demonstrated the utility of urine LF-LAM for TB diagnosis among AHD patients and the simple, user-friendly test was acceptable as part of routine care. Inclusion of urine LF-LAM test in the current diagnostic algorithm may facilitate early TB diagnosis among AHD patients.

Corrosion of steel bars embedded in reinforced concrete (RC) structures reduces the service life and durability of structures causing early failure of structure, which costs significantly for inspection and maintenance of deteriorating structures. Hence, monitoring of reinforcement corrosion is of significant importance for preventing premature failure of structures. This paper attempts to present the importance of monitoring reinforcement corrosion and describes the different methods for evaluating the corrosion state of RC structures, especially hal-cell potential (HCP) method. This paper also presents few techniques to protect concrete from corrosion.
