Introduction: The constant increase of both esthetic demands and advancement in materials and technologies have led to the development of guidelines to achieve optimal aesthetic results. These tools are useful to predict the teeth proportion and dimensions. Golden and Red proportion are the most described theories.
Aim: of present study was to evaluate the existence of both Golden and Red proportion in the maxillary anterior teeth among a North-African population.
Methods: This was an observational study performed at the Fixed Prosthetic department of the dental clinic of Monastir, Tunisia. The study included participants with full intact anterior dentition. Those with diastema or teeth crowding were excluded. For each one, an alginate impression was done. Measures were, including the perceived width and length, have been taken on casts using digital caliper. Width ratios of maxillary lateral incisor to maxillary central incisor and lateral incisor to canine were calculated.
Results: The study included 100 Tunisian participants including 97 females and 21 males. The maxillary central incisors were the largest (8.60±0.58mm) and the longest (99.71±1.14mm). The ratio was 0.89±0.09mm. Anterior teeth dimensions were not statistically not different between males and females. Significant differences were observed between calculated ratios with GP and to each other's. (p=0).
Conclusions: Either GP nor RP is applicable amongst the Tunisian Population.

The body color state is an important determinant of the value of golden severum ()-a popular ornamental fish. The use of dietary supplements to improve the color development and health of this species is unexplored. Herein, the effects of marigold extract (MG) and carophyll red (CR) are examined on the growth, body color development, antioxidant properties, and innate immunity in golden severum.

Background: Lovastatin, the main lipid-lowering component in red yeast rice, is a golden anti-lipid drug, but its long-term application is continuously challenged by potential skeletal muscle atrophy. Daidzein, an isoflavone derived from soybeans and many Chinese medicines, shows therapeutic potential in treating muscle-related diseases and metabolic disorders. However, whether daidzein can improve lovastatin-induced muscle atrophy and the specific mechanism needs to further study.

This study investigates the population divergence, hybridization dynamics, and evolutionary history of hybridizing golden-backed and red-backed flameback woodpeckers on the island of Sri Lanka, providing insights into speciation processes within an island biogeographic context. Utilizing genomic analysis based on next-generation sequencing, we revealed that the hybrid zone on this island is a complex three-way hybrid zone involving three genetically distinct populations: two cryptic populations of golden-backed in the north and one island-endemic red-backed population of in the south of Sri Lanka.

Yuebi Plus Banxia Decoction is derived from the Synopsis of the Golden Chamber(Jin Gui Yao Lue) by ZHANG Zhong-jing. With the effects of ventilating lung, discharging heat, descending adverse Qi, and relieving cough and asthma, this prescription is mainly used to treat pulmonary distension caused by phlegm heat obstructing the lungs. Currently, it is commonly used in clinical practice for the treatment of acute exacerbation of chronic obstructive pulmonary disease, acute bronchitis, pneumonia, bronchial asthma, pulmonary heart disease, and pertussis.

National Renewable Energy Laboratory, Golden, Colorado 80401, United States.
Though power conversion is an important metric for photovoltaic windows, it must be balanced with visible transmittance, aesthetics (color and haze), and thermal performance. Optical properties are often reported, but thermal performance is typically neglected entirely in photovoltaic window design. Here, we introduce the strategy of using laminate layers to improve the thermo-optical performance of perovskite-based photovoltaic insulating glass units.
