Combination of farnesyl-transferase inhibition with KRAS G12D targeting breaks down therapeutic resistance in pancreatic cancer.

Pancreatic adenocarcinoma is one of the deadliest forms of cancer with no effective therapeutic options. A KRAS mutation can be found in up to 90% of all pancreatic tumors, making it a promising therapeutic target. The introduction of new KRAS inhibitors has been a milestone in the history of KRAS mutant tumors; however, therapeutic resistance limits their efficacy.

Relationship between flap microcirculation and hard tissue changes following alveolar ridge augmentation: a prospective case series.

Objectives: To assess blood flow alterations after horizontal Guided Bone Regeneration (GBR) and to evaluate correlations between blood flow and hard tissue changes.

Method And Materials: Twelve mandibular surgical sites were involved in the current case series. GBR was carried out using a split-thickness flap design.

-Substituted AB-type phenothiazinyl porphyrins and their indium and zinc complexes photosensitising properties, cytotoxicity and phototoxicity on ovarian cancer cells.

New -substituted AB-type phenothiazinyl porphyrins and ferrocenylvinyl phenothiazinyl porphyrin were synthesised by Suzuki-Miyaura and Mizoroki-Heck cross-coupling reactions, respectively. The free porphyrins were further used in the synthesis of new indium(iii) or zinc(ii) porphyrin complexes. All porphyrins exhibit red fluorescence emission in solution, a property that remains unimpaired following internalisation in ovarian A2780 cancer cells, as evidenced by fluorescence microscopy images.

RETINOBLASTOMA-RELATED Has Both Canonical and Noncanonical Regulatory Functions During Thermo-Morphogenic Responses in Arabidopsis Seedlings.

Warm temperatures accelerate plant growth, but the underlying molecular mechanism is not fully understood. Here, we show that increasing the temperature from 22°C to 28°C rapidly activates proliferation in the apical shoot and root meristems of wild-type Arabidopsis seedlings. We found that one of the central regulators of cell proliferation, the cell cycle inhibitor RETINOBLASTOMA-RELATED (RBR), is suppressed by warm temperatures.

A glimpse into the past of Hansen's disease - Re-evaluation and comparative analysis of cases with leprosy from the Avar period of the Trans-Tisza region, Hungary.

Our knowledge of how society viewed leprosy and treated its victims in the past is still scarce, especially in geographical regions and archaeological periods from where no written sources are available. To fill in some research gaps, we provide the comparative analysis of five previously described, probable cases with leprosy from the Avar-period Trans-Tisza region (Hungary). The five skeletons were subject to a detailed macromorphological (re-)evaluation.
