The Effect of stunting on number of primary teeth eruption among 19-60 months old stunted toddlers in Panduman Village, Jelbuk, East Java
Authors: Prijatmoko Dwi , Sulistyani  , Ardhita Rezza D. 
Published: April 2024

Objective: The aim of this study was to determine the effect of growth stunting on the number of primary teeth eruption from a representative Panduman Village, Jelbuk, East Java.
Material and Methods: This is an analytic observational with a cross sectional approach study. Parents of the stunted toddlers were invited and 25 toddlers (age between 19-60 months) were participated in the study. There were 25 normal growth toddlers who had the same age range who were also invited in this study as for the normal control group. In this study, the tooth were considered to have erupted if the crown if the tooth was clinically visible through the gingival mucosa. Data was than devided into 4 (20-30, 31-40, 41-50 and 51-60) age categories, The average data for each category was analyzed with independent T test if necesary.
Results: All primary incisors have been erupted for all age category for both stunted and normal control population. The number of primary canines were significantly difference (P> 0.02) only in the 20-30 months age cateory. It may sugest that stunting affect the eruption time of primary canines. However, the number of erupted primary molars were not significantly difference in all age categories between stunted and normal controls groups.
Conclusion: Stunting potentially affect the eruption time of primary teeth. Further study involving larger number of sampel is required to conform this findings.

Published: April 2024

Objective: Keratocystic odontogenic tumor (KCOT) is a benign intraosseous tumor of odontogenic origin, making up the third most common odontogenic cyst. KCOTs arise from the remnants of dental lamina or the basal cells of the overlying oral epithelium. KCOTs are characterized by an aggressive behaviour with a relatively high recurrence rate, especially if they are associated with syndromes. Treatment of KCOTs include marsupialization, saucerization,
Methods: A 12-year-old child patient was referred to the Specialist Clinic of Oral and Maxillofacial Surgery, Cipto Mangkusumo Hospital. On physical examination, facial asymmetry, a fixated swelling and lump in right maxilla from the second molar to canine with tenderness were observed. A complete history was taken and clinical examination followed by complete enucleation with sulcular flap from 12 region until 18 regions was performed. The diagnosis was maxillary dentigerous cyst based on histopathological result after the operation.
Results: The medical history was not significant and patient was in a generally good condition with no fever, nausea, pain, or difficulty in breathing. Extra oral examination showed facial asymmetry and visible lump in the right region of the maxilla.
Conclusion: The diagnosis of maxillary KCOT expanding to maxillary sinus can be achieved with adequate datas; history, clinical, and histopathological examinations. Careful surgical approach and proper treatment decision is crucial to avoid complications according to individual case of each patient, especially in children.

Published: April 2024

Objective: Obstructive sleep apnea (OSA) is a condition where obstruction of upper airways appears periodically while patient asleep that can be complete (apnea) or partially (hypopnea). This condition is most common on male population with obese body. A prosthodontist can try to help by providing oral appliances (OA) for patient to use while they were asleep. OA were designed to thrust mandible forward and downward so that minimalize the chance for obstruction of upper airways to occur.
Case Report: A forty years old patient was complaining about his bad sleep quality. He stated that he often awakens gasping for air while sleeping for almost 3 months, he also stated that he felt exhausted and sleepy during daytime. Patient then prompted to undergo sleep test using home sleep test device ApneaLink Air from Resmed. According to the data gathered by the device, patient was diagnosed having mild sleep apnea and then treated with OA twin block. Result: Patient felt improvement on his sleep quality, even though home sleep test while using oral appliance had not been done.
Conclusion: Oral appliance can be used to improve patient with mild obstructive sleep apnea sleep cycle.

Rice is one of the most important staple food crops worldwide, especially in Asia. However, the climate change has been negatively affecting the arable land area, which leads to a severe reduction of the rice yield. In which, the salt stress is considered as one of the most critical abiotic stresses. The creation of rice varieties with salt tolerance is an urgent research direction. In this study, we successfully created two CRISPR/Cas9 vectors to introduce targeted mutations of two different positions in the promoter region of the OsSRFP1 , a gene involves in the Ubiquitination pathway and regulates important responses to multiple stresses. Cali from mature seeds of the Khang Dan 18 rice cultivar was used for Agrobacterium mediated transformation. Total 6 T0 rice lines showed CRISPR/Cas9 induced mutations in the targeted sites. Two of them were utilized for validating inheritance and segregation of induced mutations at the T1 generation. Importantly, homozygous mutant lines lacking the transgene were successfully identified at the T1 generation. These mutant lines are valuable materials for us to continue to assess gene expression, plant growth and development as well as salt tolerance in the further research work.

El mundo de la educación puede estar permeado por distintas miradas, miradas de las que parte la construcción de modelos pedagógicos, producto de sistemas educativos provenientes de varias teorías. Es así como en el presente texto se realiza un recorrido a partir de la teoría psicoanalítica sobre cómo se percibe este mundo educativo, y se revisa la manera como se relacionan estas dos disciplinas.
El recorrido realizado se fundamenta en las posiciones y postulados teóricos de algunos autores psicoanalistas como el mismo Sigmund Freud, y los llamados post – freudianos, siendo éstos últimos quienes más se sumergieron en el tema del psicoanálisis aplicado a diferentes campos, entre ellos la educación.

AbstractThe steel–concrete interface (SCI) is known to play a major role in corrosion of steel in concrete, but a fundamental understanding is still lacking. One reason is that concrete’s opacity complicates the study of internal processes. Here, we report on the application of bimodal X-ray and neutron microtomography as in-situ imaging techniques to elucidate the mechanism of steel corrosion in concrete. The study demonstrates that the segmentation of the specimen components of relevance—steel, cementitious matrix, aggregates, voids, corrosion products—obtained through bimodal X-ray and neutron imaging is more reliable than that based on the results of each of the two techniques separately. Further, we suggest the combination of tomographic in-situ imaging with ex-situ SEM analysis of targeted sections, selected based on the segmented tomograms. These in-situ and ex-situ characterization techniques were applied to study localized corrosion in a very early stage under laboratory chloride-exposure conditions, using reinforced concrete cores retrieved from a concrete bridge. Several interesting observations were made. First, the acquired images revealed the formation of several corrosion sites close to each other. Second, the morphology of the corrosion pits was relatively shallow. Finally, only about half of the total 31 corrosion initiation spots were in close proximity to interfacial macroscopic air voids, and > 90% of the more than 160 interfacial macroscopic air voids were free from corrosion. The findings have implications for the mechanistic understanding of corrosion of steel in concrete and suggest that multimodal in-situ imaging is a valuable technique for further related studies.

Similarity of symptoms with other disorders of the ENT organs, low vigilance of primary care specialists lead to delayed diagnosis and treatment increasing the risk of complications. In recent years, diagnosis and treatment of this pathology have received a higher level of attention as evidenced by increased number of publications on this topic.The review considers in detail the problems of etiopathogenesis, classification, diagnosis and treatment of spontaneous cerebrospinal fluid rhinorrhea based on current data from scientific literature.
Imaging Left-Lateral and Reverse Near-Surface Slip of the 2020 Mw 5.1 Sparta, North Carolina, Earthquake
Authors: Szymanski Eric D. , Hetland Eric A. , Figueiredo Paula M. 
Published: April 2024

ABSTRACT
Coseismic deformation of the 9 August 2020 Mw 5.1 Sparta, North Carolina, earthquake was captured by an Advanced Land Observing Satellite 2 interferogram, a Sentinel 1A/B interferogram, and differential light detection and ranging (lidar). Owing to the moderate surface deformation compared to the inherent uncertainties of interferometric data, the interferograms suffered from low signal-to-noise ratios, exacerbated by spurious signals arising from the discrepancy in resolution between the interferograms and digital elevation model used during processing. Nevertheless, coseismic slip can be imaged using graph-guided fused LASSO, where LASSO is the least-absolute shrinkage and selection operator—an inverse method that combines sparsity constraints and smoothness regularization—to infer signal from noisy and/or incomplete data. We develop five coseismic slip models, one determined only from the Sentinel 1A/B interferogram, one determined from both interferograms, one determined from all the Interferometric Synthetic Aperture Radar (InSAR) data masking potentially spurious data corresponding to industrial parks, one from lidar 3D displacements only, and one constrained by the masked InSAR and the lidar data. All five models are coseismic slip on a single fault plane, trending northwest–southeast with dips ranging from 41° to 60° to the southwest. Coseismic slip is imaged to be shallow, with predominantly oblique reverse slip extending to about 2 km depth. We find that masking the interferometric data corresponding to the industrial parks yields a coseismic slip model in better concordance with ancillary information about the Sparta earthquake and that the lidar data yield additional constraints on near-surface coseismic slip. We show that our preferred coseismic slip model is consistent with a stress regime that does not depart from an Andersonian thrust regime to a large degree, constraining that the background stress is larger than 20–30 MPa.
