Introduction: Photography is indispensable for plastic surgery. On-camera flashes can result in bleached out detail and colour. This is why most of the plastic surgery clinics prefer studio lighting similar to professional photographers'. In this article, we want to share a simple alternative to studio lighting that does not need extra space: Ring light.
Methods: We took five different photographs of the same person with five different camera and lighting settings: Smartphone and ring light; point and shoot camera and on-camera flash; point and shoot camera and studio lighting; digital single-lens reflex (DLSR) camera and studio lighting; DSLR and ring light. Then, those photographs were assessed objectively with an online survey of five questions answered by three distinct populations: plastic surgeons (n: 28), professional portrait photographers (n: 24) and patients (n: 22) who had facial aesthetic procedures.
Results: Compared to the on-camera flash, studio lighting better showed the wrinkles of the subject. The ring light facilitated the perception of the wrinkles by providing homogenous soft light in a circular shape rather than bursting flashes. The combination of a DSLR camera and ring light gave the oldest looking subject according to 64 % of responders. The DSLR camera and the studio lighting demonstrated the youngest looking subject according to 70 % of the responders. The majority of the responders (78 %) chose the combination of DSLR camera and ring light that exhibited the wrinkles the most.
Conclusions: We suggest using a ring light to obtain well-lit photographs without loss of detail, with any type of cameras. However, smartphones must be avoided if standard pictures are desired.

Bryostatins are a family of marine natural products that have garnered significant interests, as evidenced by over 40 clinical trials. However, their extremely low natural abundance has severely limited further research. Despite significant efforts, which have led to the total synthesis of seven bryostatin members by eight independent research groups, these complex molecules present persistent challenges for stereocontrolled, large-scale, and especially divergent synthesis.

Kaposi's sarcoma-associated herpesvirus (KSHV) employs diverse mechanisms to subvert host immune responses, contributing to its infection and pathogenicity. As an immune evasion strategy, KSHV encodes the Membrane-Associated RING-CH (MARCH)-family E3 ligases, K3, and K5, which target and remove several immune regulators from the cell surface. In this study, we investigate the impact of K3 and K5 on lymphotoxin receptor (LTβR) ligands, LTβ and LIGHT, which are type II transmembrane proteins and function as pivotal immune mediators during virus infection.

Cellulose, the most abundant biopolymer on Earth, is biodegradable, nontoxic, and derived from renewable sources. Its properties and applications depend on the extraction methods and sources, making plant waste reuse a sustainable production option. This study aimed to assess the potential of cowpea pod skin () as a source of microcellulose (CPMC) using a chemical-mechanical process involving ball milling combined with acid hydrolysis.

Despite the many advantages for industrial mass production, vacuum-deposited organic solar cells (OSCs) suffer from low efficiency, primarily due to the limited molecular library of small-molecule donor and acceptor materials, which remains a significant challenge. Herein, two donor-acceptor-acceptor (D-A-A)-configured small-molecule donors, named TTBTDC and TTBTDC-F were synthesized, using 8H-thieno[2',3':4,5]thieno[3,2-b]thieno[2,3-d]pyrrole (TTP) as a new fused-ring donor unit. Benefiting from the strong electron-donating ability of the TTP moiety and the adoption of the D-A-A molecular configuration, these molecules exhibited strong visible and near-infrared absorption as well as deep-lying highest occupied molecular orbital (HOMO) energy levels.

Background: In their care of terminally ill patients, palliative care physicians and oncologists are increasingly predisposed to physical and emotional exhaustion, or compassion fatigue (CF). Challenges faced by physicians include complex care needs; changing practice demands, and sociocultural contextual factors. Efforts to better understand CF have, however, been limited.
