INTRODUCTION: the use of skin lightening products (SLPs) by women is poorly documented in Africa, with statistics from some countries entirely missing. This study assessed knowledge, perceptions, practices and factors associated with health risk awareness of African Basotho women towards SLPs. METHODS: this was a questionnaire-based cross-sectional study based on convenience sampling of females in secondary/high schools, universities, factories and business offices in Maseru City, Lesotho...

Burgeoning morbidity and mortality due to COVID-19 pandemic including the peaks in outbreaks due to different variants have attracted global attention. Although the development and rolling out of vaccines have been impressive, low- and middle-income countries suffer from a double burden: (1) lack of adequate vaccines; and (2) low vaccine uptake (vaccine hesitancy). The main objective of this study was to explore perceptions around COVID-19 and vaccine hesitancy among urban and rural population in Western Nepal...

BACKGROUND: The aesthetic appearance of the skin, with the emergence of wrinkles, blemishes, and infraorbital hollowing, can be a cause of social distress and is a process exacerbated by aging. The presence of skin imperfections and aging is partly due to a loss of hyaluronic acid (HA), which normally contributes to a maintain a healthy and voluminous skin. Attempts to restore volume and revert the signs of aging have therefore focused on the use of dermatologic fillers based on HA. AIM: Here, we tested the safety and efficacy of MelHA®-Monophasic Elastic Hyaluronic Acid (Concilium FEEL® filler products) containing HA at different concentrations and injected at different sites according to recommendations...

Lignin has been suggested as a promising candidate for cosmetic applications due to its remarkable potential to absorb ultraviolet rays and distinctive antioxidant activity. This study aims at evaluating the performance of lignin from sugarcane bagasse (SCB) as natural UV blocker, antioxidant, and pigment. Lignin was extracted from SCB, characterized and incorporated into a blemish balm (BB) cream. The biological potential, concretely, in vitro and in vivo sun protection factor (SPF) and in vitro UVA-PF, and safety were assessed...

Identification and segregation of citrus fruit with diseases and peel blemishes are required to preserve market value. Previously developed machine vision approaches could only distinguish cankerous from non-cankerous citrus, while this research focused on detecting eight different peel conditions on citrus fruit using hyperspectral (HSI) imagery and an AI-based classification algorithm. The objectives of this paper were: (i) selecting the five most discriminating bands among 92 using PCA, (ii) training and testing a custom convolution neural network (CNN) model for classification with the selected bands, and (iii) comparing the CNN's performance using 5 PCA bands compared to five randomly selected bands...

Dark Red Norland is an important potato cultivar in the fresh market due to its attractive bright, red colour, and good yield. However, skin blemishes such as silver patch, surface cracking, and russeting can negatively influence the tuber skin quality and marketability. It is well known that potato is a drought-sensitive plant. This study was conducted to determine whether irrigation would affect Dark Red Norland's yield and skin quality. A three-year field trial was conducted by Peak of the Market in Manitoba, Canada...

Border rows of grain sorghum were planted along two to four sides of an organic Granadero tomato crop in North Florida to reduce fruit injury caused by native and invasive stink bugs. During the 2-yr study, 14 species of stink bugs were encountered, six only in sorghum: Piezodorus guildinii (Westwood) (Hemiptera: Pentatomidae), Thyanta spp., Oebalus pugnax (Fabricius), Chinavia hilaris (Say), C. pensylvanica (Gmelin), and Mormidea pama (Rolston). There were four species only in tomato: Euschistus obscurus (Palisot de Beauvois), E...

Oleocellosis is a physiological disorder in citrus fruit and causes extensive economic damage due to the surface blemishes it creates. It was reported that oleocellosis always occurs during preharvest maturation and postharvest storage. In the present study, the oleocellosis incidence of Jincheng orange, Navel orange and Ponkan were found to be different during preharvest maturation, however, no differences were found during postharvest storage. Additionally, it was interesting that the outbreak period of oleocellosis incidence was 0-12 d during postharvest storage...

Wireworms are primary pests of potatoes in Canada. Presently, the highly toxic organophosphate phorate (i.e., Thimet 20G) is the only effective insecticide in use in Canada. As such, there is an urgent need for novel alternative treatments that provide competitive tuber blemish protection and wireworm reduction with a safer human and environmental portfolio. Herein we evaluated broflanilide, a novel meta-diamide insecticide for both tuber protection and wireworm mortality. When evaluated in field trials in Agassiz, British Columbia over 6 yr, broflanilide applied as a seed piece treatment (SPT) to mother tubers at 1...

Microscopic colitis is a form of colonic inflammation that presents with chronic nonbloody diarrhea that can only be diagnosed histologically with biopsies obtained during colonoscopy. We report a rare case of isotretinoin-induced microscopic colitis in a patient who was prescribed this medication for nodular acne with a 1-year history of nonbloody diarrhea, bloating, cramping, and foul-smelling gas. Cessation of this medication in addition to initiating treatment with budesonide resulted in remission of the patient's symptoms...

Nectarines are perishable fruits grown in Southern Europe, valued for their sensorial properties. Chilling is used in the supply chain for Northern European consumers, while Southern European consumers can access fresh, locally grown fruit or cold-stored supermarket fruit. Cold storage and fruit ripening affect texture and flavour. Here a consumer survey and hedonic testing compared the appreciation of nectarines (cv. Big Top) in Italy and at two UK sites (n = 359). Fruit was at the commercial harvest stage, or stored at 1 °C or 5 °C for seven days, then sampled after two days' (Italy and one UK site) or four days' (second UK site) ambient recovery...

"San-Bai Decoction" (SBD) has been a traditional Chinese medicine compound preparation for replenishing Qi and promoting blood circulation, whitening skin, and removing blemishes since ancient times. However, its chemical composition and antioxidant activity are not clear thus far, which limits the in-depth study on its pharmacodynamic material basis and efficacy. The objective of this study was to establish the fingerprint profile of SBD, assess its antioxidant activity by measuring 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging ability, and find the spectrum-effect relationship of SBD by Grey Relation Analysis (GRA) and Partial Least Squares Regression (PLS)...

As novel generated 2D materials, metal-organic layers (MOLs) have recently emerged as a potential platform for photocatalytic CO2 reduction reaction (PCO2 RR). Such 2D structures negate the blemish of low-density catalytic sites and low electron transmission efficiency on the surface of metal organic frameworks (MOFs), while retaining the advantage of low expenditure when using earth-abundant metal nodes and meritorious applicability in the PCO2 RR. Herein, it is reported that the 2D ultrathin layer material with bis-metallic catalytic sites (Ni-O metal node and the Ni-N metal site) from bidentate ligand 2,2'-bipyridine-5,5'-dicarboxylate (H2 bpydc) and nickel(II) remarkably boosts the visible light-driven PCO2 RR performance with a CO yield of 2400 mmol g-1 for 18 h and a selectivity up to 99 %...

Targeted marketing and media may serve as potential sources of health information for consumers, influencing knowledge, practices, perception, and utilization of health care services. In addition to this vulnerable consumerism, there are barriers to healthy consumerism including exposure to different sources or lack thereof, lack of knowledge, inadequate transportation, or proximity to stores, cost, and marketing of products that are not suitable for all skin types. We conducted a multi-center “Skin of Color Skin Care Needs” survey to characterize the skin care practices, concerns, and habits of both persons of color and non-Hispanic whites to evaluate barriers and influences on product choice and behaviors in these populations...

Citrus black spot (CBS) is a disease caused by the fungus Phyllosticta citricarpa that affects citrus plants, causing fruit blemish and premature drop that result in severe economic losses in commercial citrus orchards. However, CBS symptoms and effects may vary depending on the citrus species: Citrus limon (lemon) is susceptible and highly affected by the disease, while no CBS-related damage has ever been observed for Citrus latifolia (Tahiti lime), implying that it must be resistant to the disease. The difference in the response to this disease provided the opportunity to gain insight into the metabolites responsible for the resistance by comparison of the metabolomic profiles of these two citrus species...

Benefitting from the special structure of the leaf cuticle layer, plants have natural hydrophobicity and anti-fouling abilities. Inspired by the leaf surface structure, a biomimetic modification strategy was raised to improve the surface hydrophobicity of polyacrylate coating for controlled release fertilizer. Double-layer (polyacrylate and carnauba wax) coated fertilizer was obtained after biomimetic modification. The quality of controlled release fertilizer modified with the carnauba wax was greatly enhanced, and the coating material was effectively saved...

Gorlin-Goltz syndrome is a hereditary autosomal dominant condition with high penetrance and varied phenotypic expressiveness that can appear spontaneously. It is estimated that between 30% and 50% of people with this disease do not know if any of their family members have had it. Patched (PTCH), a tumor suppressor gene found on the 9q22.3 chromosome, has been identified as the cause of Gorlin-Goltz syndrome. This case emphasizes the necessity of awareness of this uncommon illness in young people who do not have any skin blemishes...

A congenital cystic eyeball is an extremely rare condition, with only 52 cases reported in the literature to date. An orbital cyst replaces the eyeball which occurs due to the complete or partial failure in invagination of the primary optic vesicle during the fourth week of gestation. We discuss a case of a congenital cystic eyeball in a 14-year-old female who presented to us for a cosmetic blemish due to a large swelling in the right eyelid with the absence of a right eyeball since birth. She underwent removal of the cyst followed by an orbital implant and later prosthesis...

Deep learning-based methods, especially convolutional neural networks, have been developed to automatically process the images of concrete surfaces for crack identification tasks. Although deep learning-based methods claim very high accuracy, they often ignore the complexity of the image collection process. Real-world images are often impacted by complex illumination conditions, shadows, the randomness of crack shapes and sizes, blemishes, and concrete spall. Published literature and available shadow databases are oriented towards images taken in laboratory conditions...

BACKGROUND: A scar can be defined as a mark or a blemish resulting from a healed wound. All surgical incisions give rise to scars and approximately 15% have excessive scars. Some scars are thin lines which are almost unnoticeable, whereas others become abnormal when the amount of fibrosis is excessive or suboptimal or when it causes functional disability or aesthetic distress to the patient. The conversion of normal scarring to hypertrophic scarring occurs six to eight weeks after surgery as a result of increasing scar tension...
