Smell throughout the life course

Evolutionary Anthropology Issues News and Reviews, Год журнала: 2024, Номер 33(4)

Опубликована: Май 5, 2024

Abstract The sense of smell is an important mediator health and sociality at all stages life, yet it has received limited attention in our lineage. Olfaction starts utero participates the establishment social bonds children, romantic sexual relationships after puberty. Smell further plays a key role food assessment danger avoidance; modern societies, also guides consumer behavior. Sensory abilities typically decrease with age can be impacted by diseases, repercussions on well‐being. Here, we critically review current understanding human olfactory communication to refute outdated notions that low importance. We provide summary biology olfaction, give prospective overview importance throughout life course, conclude outline limitations future directions this field.

Epidemiological analysis of axillary apocrine bromhidrosis in China: a survey from Chinese higher education students

Frontiers in Medicine, Год журнала: 2023, Номер 10

Опубликована: Ноя. 6, 2023

There are few epidemiological data on axillary apocrine bromhidrosis (AAB) in the Chinese population, making it impossible to accurately estimate its prevalence or impact individuals.To of AAB China, and survey compare psychological status individuals with without AAB.Students several universities China were surveyed online for AAB, was calculated. The Symptom Checklist 90 (SCL-90) used evaluate status.The students 7.5% (194/2571). projected number higher education about 3 million. onset age mainly between 11 20 years old (79.90%, 155/194). 68.04% (132/194) had a positive family history, 60.30% (117/194) wet earwax. Individuals often felt depression, anxiety, loneliness social alienation, scored significantly nine primary symptom dimensions than AAB.AAB affects small proportion but large numbers population. West East-Asia have different perception, recognition treatment preferences AAB.

Comparative Study of 1444 nm Laser Monotherapy versus Integrated Liposuction in the Treatment of Axillary Osmidrosis

Medicina, Год журнала: 2024, Номер 60(7), С. 1151 - 1151

Опубликована: Июль 17, 2024

The 1444 nm wavelength Neodymium:Yttrium-Aluminum-Garnet (Nd:YAG) laser treatment is an efficient method for treating axillary osmidrosis (AO); however, it has a relatively low persistence. To address this issue, we performed integrated liposuction surgery with to treat AO and compared the results those of group treated only laser.

Consistent social odor representation across seven languages: the Social Odor Scale translation and validation

Опубликована: Фев. 17, 2024

The Social Odor Scale (SOS) is a 12-item questionnaire initially developed and validated in Italian German to investigate awareness of social odors, which are odors emanating from the human body that convey diverse information evoke various emotional responses. scale includes total score three subscales representing respective categories: romantic partner, familiar, strangers. Here we aimed replicate validation versions SOS, translate validate SOS into multiple additional languages (French, English, Dutch, Swedish, Chinese), explore whether factor structure each translated version aligns with original versions. Confirmatory Factor Analysis (CFA) supported scale’s structure, yielding good fit across all languages. Notable differences mean scores were observed among different languages: Swedish participants exhibited lower odor compared other groups, whereas Chinese reported higher Dutch participants. Further, correlated respondents’ geographical location, (i.e., northern) latitudes linked awareness. These results corroborate as valid reliable instrument, especially for Familiar Stranger factors, emphasizing influence individual factors geographic location on

Identification of a higher C–S lyase activity of Staphylococcus hominis in volunteers with unpleasant axillary odour

International Journal of Cosmetic Science, Год журнала: 2024, Номер 46(6), С. 1088 - 1096

Опубликована: Сен. 16, 2024

Abstract Objective Excessive and unpleasant odours that emanate from the skin can induce bromhidrosis substantially impair a person's quality of life. Enzymatic pathways generating are well detailed, among them, C–S lyase is one enzymes involved in conversion non‐volatile precursors into thiol‐type malodorous volatile molecules such as 3M3SH. This study aimed to investigate variation axillary odour intensity correlated with Staphylococcus ( S .) hominis activity within group volunteers after physical activity. Methods First, 24 same ethnicity standardized hygienic alimentary practices participated supervised indoor cycling Following this session, worn T‐shirts were recovered enable olfactory evaluation by qualified experts. To go further, microbiota zone each volunteer was sampled bacterial relative abundance investigated using 16S rRNA metasequencing. Then, . isolates obtained culturomics these samples measured spectrofluorometry protein crude extracts. Results The revealed panel, two groups significantly distinct.

Consistent social odor representation across seven languages: the Social Odor Scale translation and validation

Chemical Senses, Год журнала: 2024, Номер 49

Опубликована: Янв. 1, 2024

Abstract The Social Odor Scale (SOS) is a 12-item questionnaire initially developed and validated in Italian German to investigate self-reported awareness of social odors, which are odors emanating from the human body that convey diverse information evoke various emotional responses. scale includes total score 3 subscales representing respective categories: romantic partner, familiar, strangers. Here, we aimed (i) replicate validation versions SOS, (ii) translate validate SOS into multiple additional languages (French, English, Dutch, Swedish, Chinese), (iii) explore whether factor structure each translated version aligns with original versions. Confirmatory Factor Analysis (CFA) supported scale’s structure, yielding good fit across all languages. Notable differences mean scores were observed among different languages: Swedish participants exhibited lower odor compared other groups, whereas Chinese reported higher Dutch participants.

Interplay of human ABCC11 transporter gene variants with axillary skin microbiome functional genomics

Scientific Reports, Год журнала: 2024, Номер 14(1)

Опубликована: Ноя. 14, 2024

The human armpit microbiome is metabolically entangled with skin cell physiology. This "meta-organism" symbiotic mutualism results in sweat either or without odor (osmidrosis), depending on host ABCC11 gene haplotypes. Apocrine metabolism produces odorless S-glutathione conjugate that transferred by transporters into secretory vesicles, deglutamylated to S-Cys-Gly-3M3SH thiol, and exuded surface. An anthropogenic clade of bacteria then takes up the thiol bioconverts it malodorous 3-methyl-3-sulfanylhexan-1-ol (3M3SH). We hypothesized a familial meta-organism association non-synonymous SNP rs17822931 interplaying 3M3SH biosynthesis. Subjects were genotyped for SNPs, their haplotypes correlated axilla DNA sequencing profiles predicted metagenome functions. A multigeneration family pedigree revealed Mendelian autosomal recessive pattern: C allele bacterial Cys-S-conjugate β-lyase (PatB) known Staphylococcus hominis biosynthesis from precursor; PatB was rescinded hosts homozygous TT alleles encoding loss-of-function mutation. posit functional key delivering precursors shape heritable niche conditions favorable harboring having genomics production. provides existential insights evolution global regional population ancestries.
