Hepatocellular carcinoma (HCC) with portal vein tumor thrombosis (PVTT) is associated with a dismal prognosis. Atezolizumab plus bevacizumab (atezo-bev) is the recommended palliative treatment, and approximately 10% of the patients may experience a complete response (CR), according to the mRECIST criteria. The treatment duration is until disease progression or unacceptable side effects occur. Long-term continuation can cause potential toxicities and a substantial financial burden, making early treatment discontinuation a viable option. This report describes durable CR after discontinuing atezo-bev treatment in three patients with HCC and PVTT.

Purpose:
The bisecting angle technique (BAT) encounters difficulties in positioning the X-ray cone and aligningthe central beam with the tooth. To address this, a rectangular laser featuring a pointed light was integrated into theintraoral X-ray cone. This study evaluated its effectiveness in improving radiograph quality and minimizing errors.
Materials and Methods:
Fifty fifth-year Bachelor of Dental Surgery students were divided into 3 groups. Group1 (n = 16) used the paralleling technique, group 2 (n = 17) employed the conventional BAT, and group 3 (n = 17) utilized the laser-assisted BAT on mannequins. Two independent oral radiologists assessed the quality of the radiographs, categorizing the images as either diagnostically acceptable or not acceptable. Inter-group comparisons of quality and error rates were conducted using the chi-square test (significance level: P<0.05).
Results:
The paralleling technique group produced 77.5% diagnostically acceptable radiographs and 22.5% that were not diagnostically acceptable. These percentages were 65.3% and 34.7%, respectively, in the conventional BAT group and 75.3% and 24.7%, respectively, in the laser-assisted BAT group, showing results similar to the paralleling technique group. The quality of radiographs differed significantly among the groups (P<0.05). The percentage of error-free radiographs was 38.1% in the paralleling technique group, 20.6% in the conventional BAT group, and 40.0% in the laser-assisted BAT group, with these differences being statistically significant (P<0.05).
Conclusion
The device produced higher acceptability and fewer radiographic errors than the conventional BATtechnique, suggesting accurate adjustment of the X-ray cone and central beam to the desired teeth.

Dunia kosmetik sekarang berubah fokus kepada produk penjagaan kulit yang menggunakan ekstrak semulajadi
seperti biji halba. Tujuan kajian ini adalah untuk merumuskan krim kulit kosmeseutikal bersifat antioksidan
dengan menggunakan minyak pati biji halba (Trigonella foenum-graecum) dan seterusnya menilai pelbagai
ciri fisiokimianya termasuk ujian pemusnahan radikal bebas, penilaian organoleptik, pencirian fizikal, ujian
kestabilan dan ujian biokeselamatan. Kepekatan minyak pati 300μL/mL menunjukkan aktiviti antioksidan yang
paling tinggi secara signifikan pada 9.58% dan formulasi krim kulit dirumuskan menggunakan emulsi minyak
dalam air dengan peratusan minyak pati yang berbeza (3%, 5% dan 10%). Ujian pemusnahan radikal juga
dijalankan ke atas formulasi krim kepekatan minyak pati 3% dan ianya menunjukkan aktiviti antioksidan tertinggi
yang signifikan (p<0.05) pada 87% serta mempamerkan sifat organoleptik yang memuaskan dengan pH 4.55.
Ujian kestabilan semua formulasi telah dijalankan selama 90 hari dan hasilnya menunjukkan bahawa formulasi
yang disimpan pada suhu bilik, mempamerkan nilai pH dan kebolehsebaran yang lebih baik berbanding formulasi
yang disimpan pada 4°C. Formulasi krim juga diuji dengan ujian saringan biokeselamatan in vitro hemolisis yang
menunjukkan ketiadaan perengsa dan bahan toksik dalam krim yang dirumuskan. Ujian sensitiviti kulit semua
formulasi krim terhadap sukarelawan melaporkan tiada reaksi kulit. Hasil kajian menunjukkan minyak pati biji
halba mempunyai sifat antioksidan yang tinggi dan boleh diformulasikan dalam bentuk krim kulit kosmeseutikal
yang selamat. Walau bagaimanapun, ujian tambahan kosmeseutikal dan dermatologi diperlukan untuk penilaian
lanjut manfaat krim yang dirumuskan.

Background:
Oral cavity cancers, the second most common type in India, are responsible for 10% of the overall cancer burden. With a recurrence rate of 30% to 40% and a 5-year survival rate of 50%, these malignancies account for substantial morbidity and mortality. Despite advances in treatment modalities, survival rates following treatment completion have not improved significantly. The present study aimed to establish specific epidemiological and pathological factors responsible for recurrence after treatment completion in buccal mucosa cancers.
Methods:
A retrospective analysis of the data of 116 patients treated for biopsy-proven cancers of the buccal mucosa was undertaken 1 year after treatment completion. Factors such as age, sex, education, lymphovascular invasion, extranodal extension (ENE), perineural invasion, depth of invasion, and pathological margin status were compared between patients who presented with recurrence and those who did not. Statistical significance was set at p< 0.05.
Results:
Of the 116 patients, 40 (34.5%) developed a recurrent disease within 1 year. The mean age of the study population was 43.3 years, and males constituted 91.4% of the included patients. Ipsilateral buccal mucosa was the commonest site of disease recurrence. Neck node metastasis, ENE, and margins of resection < 5 mm were significantly related to the recurrence of disease. However, surprisingly, lymphovascular invasion, perineural invasion, and depth of invasion > 10 mm did not show statistically significant associations.
Conclusion
Neck node metastasis, ENE, and margins of resection < 5 mm were the histopathological factors associated with recurrence in cancers of the buccal mucosa.

Genomics & Informatics 2023;21(1):e5-
Neisseria gonorrhoeae is a Gram-negative aerobic diplococcus bacterium that primarily causes sexually transmitted infections through direct human sexual contact. It is a major public health threat due to its impact on reproductive health, the widespread presence of antimicrobial resistance, and the lack of a vaccine. In this study, we used a bioinformatics approach and performed subtractive genomic methods to identify potential drug targets against the core proteome of N. gonorrhoeae (12 strains). In total, 12,300 protein sequences were retrieved, and paralogous proteins were removed using CD-HIT. The remaining sequences were analyzed for non-homology against the human proteome and gut microbiota, and screened for broad-spectrum analysis, druggability, and anti-target analysis. The proteins were also characterized for unique interactions between the host and pathogen through metabolic pathway analysis. Based on the subtractive genomic approach and subcellular localization, we identified one cytoplasmic protein, 2Fe-2S iron-sulfur cluster binding domain-containing protein (NGFG RS03485), as a potential drug target. This protein could be further exploited for drug development to create new medications and therapeutic agents for the treatment of N. gonorrhoeae infections.
