“…It is also possible that lateralization of skin temperature is independent of injury. Studies in humans report that temperatures are cooler on the left side of the body compared with the right in healthy adults, which the authors suggest may result from cerebral or peripheral immune asymmetry (Rimm-Kaufman and Kagan, 1996;Demirel et al, 2016). However, the inconsistent findings we found for surface temperature across studies in the current paper suggest that this asymmetry may not be biologically meaningful.…”

Hot-iron disbudding, the process of cauterizing the horn buds of calves or goat kids at an early age to prevent horn growth, is routinely practiced in dairy production. The wounds take weeks to heal and are painful to touch throughout this time. Possible strategies to hasten the healing of disbudding wounds are not well understood, but the type of iron used may be an important factor to consider. When evaluating strategies to hasten healing, a within-subjects design may be preferable, but laterality effects might act as a potential source of variation and confounding in this type of experiment. Our objectives were to compare healing after disbudding with 2 commercially available irons, and to determine whether wounds healed differently on the left versus the right side of the head. Ten Holstein calves 4 to 10 d of age were disbudded using the Rhinehart X50A electric disbudder (Rhinehart Development Corp., Spencerville, IN) on one horn bud and the Portasol gas disbudder (Portasol USA, Elmira, OR) on the other; side (left vs. right) was balanced between treatments. We scored wounds daily for the presence of 6 tissue types: attached necrotic tissue, detached necrotic tissue, exudate, granulation, crust, and epithelium. Surface temperature and size of the wound were measured twice-weekly using thermal and digital photographs, respectively. The type of iron used did not affect latency to re-epithelialize, which took on average (mean ± standard deviation) 53 ± 3 d and 55 ± 3 d for Portasol and Rhinehart wounds, respectively (range: 40-70 d). However, compared with Portasol wounds, those from the Rhinehart had fewer days of granulation tissue and tended to have more days of detached necrotic tissue. The Portasol tip had a smaller total surface area than the Rhinehart, which may have resulted in a less severe burn, causing the necrotic tissue to fall off sooner. The left side tended to re-epithelialize faster than the right side (mean ± standard error: left 51 ± 3 d; right 57 ± 3 d) and have fewer days of crust. Left-sided wounds were also cooler and tended to be smaller than those on the right. To assess the external validity of these laterality effects in our primary experiment (experiment A), we analyzed wound healing data from 2 other disbudding studies, one on calves (experiment B) and one on goat kids (experiment C). We observed laterality effects in the opposite direction in Experiment B, but negligible effects in experiment C, indicating that the differences in laterality had low external validity; the biological meaning of this asymmetry is unclear. Nonetheless, if using a within-subjects design, asymmetries in wound healing should be considered to avoid confounding effects. In conclusion, wounds from both irons took 7 to 8 wk to heal, on average; other strategies to accelerate healing should be explored.

“…Besides, this relationship was found to be stronger on the right wrist in accordance with Demirel et al. 107 According to Demirel et al., such asymmetry may be associated with the peripheral immune asymmetry or asymmetric lymph node distribution.…”

“…Several studies have investigated and found an asymmetry between the right and left sides of the human body related to the measurement of skin temperature and EDA. 107 – 110 These results could explain the reason why some variables in our study are correlated only with EDA and/or skin temperatures on the right wrist and not on the left and vice versa. Besides, this relationship was found to be stronger on the right wrist in accordance with Demirel et al.…”

. Significance: Functional near-infrared spectroscopy (fNIRS) enables measuring the brain activity of two subjects while they interact, i.e., the hyperscanning approach. Aim: In our exploratory study, we extended classical fNIRS hyperscanning by adding systemic physiological measures to obtain systemic physiology augmented fNIRS (SPA-fNIRS) hyperscanning while blocking and not blocking the visual communication between the subjects. This approach enables access brain-to-brain, brain-to-body, and body-to-body coupling between the subjects simultaneously. Approach: Twenty-four pairs of subjects participated in the experiment. The paradigm consisted of two subjects that sat in front of each other and had their eyes closed for 10 min, followed by a phase of 10 min where they made eye contact. Brain and body activity was measured continuously by SPA-fNIRS. Results: Our study shows that making eye contact for a prolonged time causes significant changes in brain-to-brain, brain-to-body, and body-to-body coupling, indicating that eye contact is followed by entrainment of the physiology between subjects. Subjects that knew each other generally showed a larger trend to change between the two conditions. Conclusions: The main point of this study is to introduce a new framework to investigate brain-to-brain, body-to-body, and brain-to-body coupling through a simple social experimental paradigm. The study revealed that eye contact leads to significant synchronization of spontaneous activity of the brain and body physiology. Our study is the first that employed the SPA-fNIRS approach and showed its usefulness to investigate complex interpersonal physiological changes.

“…In our study, there was no statistical difference in the pain, edema, and trismus values after extraction between the right-handed groups 3 and 4 and the lefthanded groups 1 and 2, suggesting that there was also no difference in inflammation in the extraction areas. Recent studies have focused on whether the number, size, and ultrastructural features of lymph nodes on the left and right sides of the body are different in individuals with different hand preferences (36)(37)(38).…”

Objective: Individual preference of using right or left hand for doing various hand workings, is the most easily observable form of the cerebral lateralization. It was stated that, among the right or left hand dominant individuals, there is an immunological asymetry, and a difference in motor control, visuospatial skills, and in the incidence of a number of disease. The aim of the study was to investigate pain, edema, trismus following the mandibular third molar extraction in patients with different hand preference. Amaç: Bireyin çesitli el işlerini yapmak için sağ veya sol elini tercih etmesi serebral lateralizasyonun en kolay gözlenebilen şeklidir. Sağ veya sol eli dominant olan kişiler arasında motor kontrol, vizyospasyal görevleri yerine getirmede, çeşitli hastalıkların görülme insidansında farklılıklar ve immün asimetri olduğu söylenmiştir. Bu çalışmada, mandibular 3. molar çekimini takiben görülen ağrı, ödem, trismusun el tercihi farklı olan hastalarda değerlendirilmesi amaçlanmıştır. Gereç ve Yöntemler: Çalışmaya, sağ ve sol mandibular gömülü üçüncü molar dişlerin çekiminin gerekli olduğu 43 hasta dahil edildi. Aynı hastadan sağ ve sol mandibular gömülü diş çekimi 30 gün arayla yapıldı. 4 hasta grubu oluşturuldu; 1) El tercihi sol-sağ (sağ mandibular 3.molar dişi çekilen) 2) El tercihi sol-sol 3) El tercihi sağ-sağ 4) El tercihi sağ-sol. Ağrı, ödem ve trismusun operasyondan önce ve sonra karşılaştırılması için ölçümler yapıldı.
