The wound healing potential of Hedychium spicatum Sm. and Zinnia peruviana (L.) ethanolic extracts against excision wound model in rats.

Medicinal plants used for wound healing, are key to unlock the doors for combating the resistance of pathogens by provision of new source of compounds. This study is aimed to evaluate and compare the wound healing properties of ethanolic extract of Hedychium spicatum Sm. rhizome and of Zinnia peruviana's leaves and roots. Albino rats were divided into 10 groups (n=6), control, positive control, negative control, untreated, Hedychium spicatum Sm. (125mg/kg), Hedychium spicatum Sm (250mg/kg), Zinnia peruviana (L.)(Leaves) (125mg/kg), Zinnia peruviana (L.) (Leaves) (250mg/kg), Zinnia peruviana (L.)(Roots) (125mg/kg), Zinnia peruviana (L.)(Roots) (250mg/kg) respectively. Excision wound of 1.5cm wound was inflicted on the dorsal side of each rat except control group. 5% CMC gel, fusidic acid and extract gels were applied topically once daily on the wound area which was measured at intervals of 3 days until epithelization and complete wound closure. Different biochemical markers were analyzed in both blood and skin to validate the wound healing potential of these plants. Topical application of an ethanolic extract of Hedychium spicatum Sm. (250mg/kg) had significant (p ˂ 0.001) rate of wound healing and reduced epithelization period. Marked amelioration of hydroxyproline content, remarkable results on histopathological changes, reduction in oxidative stress was observed with Hedychium spicatum Sm. ethanolic extract at dose level of 250mg/kg in comparison with untreated group. This study concluded that the Hedychium spicatum Sm. rhizome ethanolic extract gel is effective in wound repair and may possess potential for the development of dermatologic preparation for topical diseases.

Taxonomic significance of seed macro-micromorphology of Turkish Alcea L. (Malvaceae) through light microscopy and scanning electron microscopy.

Seed morphological properties of 19 taxa belonging to the genus Alcea L. (Malvaceae) distributed in Turkey were investigated using a light microscope and scanning electron microscope to identify their characters and to evaluate their diagnostic value. The seeds are reniform with a rounded apex and base, reniform in shape, and light to dark brown, grayish-brown, or blackish-brown in color. The seed length ranges from 2.22 to 6.5 mm and seed width from 1.72 to 6.5 mm. The indumentum at the ventral and dorsal regions of the seed differs in density. Three types of seed coat ornamentations were observed: reticulate, reticulate-rugulate, and reticulate-ruminate on the dorsal and lateral faces. Principal component analysis was used to evaluate the important seed morphological characteristics among the taxa studied, with four components accounting for 90.761% of the total variance. Numerical analysis revealed that seed size, color, seed surface patterns on dorsal and lateral sides, indumentum at dorsal and ventral regions, and periclinal surface sculpture of epidermal cells are particularly the most useful variables for discriminating the Alcea taxa. The findings also showed a partial relationship among the Alcea taxa clusters, based on seed morphology and the systematics of these taxa, based on general macromorphology. Taxonomic key using the seed features is provided to identify the species studied. The current work will contribute to the knowledge about the family Malvaceae, and microscopic macro-micromorphological analysis can be used for identification by the taxonomists for further studies on this family. RESEARCH HIGHLIGHTS: Seed color, indumentum and surface sculpturing have systematic value for separating the taxa. Seed morphology of the Alcea taxa was studied via light microscope and scanning electron microscope. Numerical analysis provided the contribution of seed characters to taxa relationships.

Patient Invaded by 99 Mango Fly Larva - A Case Report

We report a 35-year-old patient that presented himself to volunteering doctors in the slums of Nairobi, Kenya. The patient has been suffering of a sensation of crawling on his back and the dorsal side of his arms. Furthermore, he mentioned multiple painful swelling increasing in size.

A new species of Ptenothrix Börner, 1906 (Collembola, Symphypleona, Dicyrtomidae) from South Korea.

A new species of Collembola, Ptenothrix koreanensis sp. nov., is described and illustrated based on specimens from South Korea. It was found in a coniferous forest dominated by the Korean pine Pinus koraiensis Siebold & Zuccarini. Ptenothrix koreanensis sp. nov. is characterized by a peculiar color pattern in which most of its median dorsal side of the large abdomen is plain milky white. This new species also has the formula of 1, 1, 2, 2, 1, 3 of median spiny chaetae on the clypeal area of the head, and the formula of 6, 5, 5, 4 of prelabral and labral chaetae. These characteristics make it easy to distinguish the new species from other two possibly related species, P. ciliophora Yosii & Lee and P. saxatilis Yosii & Lee. Apart from these characteristics, the new species can also be separated from another possibly related species, P. higashihirajii Yosii, by the morphology of ps1 and pi2 chaetae on the small abdomen of the female. An identification key for the East Asian species of Ptenothrix is also provided.

Diagnostic performance of high-resolution ultrasound in the evaluation of intrinsic and extrinsic wrist ligaments after trauma.

To investigate the role of ultrasound (US) in the evaluation of intrinsic and extrinsic ligaments of the wrist with magnetic resonance arthrography (MRA) as the reference standard. This prospective study included patients referred for MRA after wrist trauma. US examination was performed just before MRA. On the dorsal and palmar sides of the wrist, the intrinsic interosseus and midcarpal, extrinsic, and collateral ligaments were evaluated. MRA was performed on a 1.5-T unit. In the first 20 patients included, ligament thickness was independently assessed using US and MRA and thickness reproducibility was calculated. Ligament integrity was evaluated in all patients. 38 patients (22 men, 16 women; mean age: 38 years) were included. Ligament thickness reproducibility ranged between 44% for the palmar ulnocapitate ligament and 71% for the palmar scaphotriquetral ligament. US had a sensitivity, specificity, positive and negative predictive values, and accuracy of 100% in the identification of tears of the palmar (n=8) and dorsal (n=3) bands of the scapholunate ligament and the ulnar collateral ligament (n=3). It had a sensitivity of 100%, specificity of 97%, positive predictive value of 50%, negative predictive value of 100%, and accuracy of 97% in the identification of tears of the palmar ulnolunate ligament (n=1). Compared to MRA, US showed good reproducibility in the assessment of wrist ligament thickness and similar accuracy with respect to identifying tears of the scapholunate, palmar ulnolunate, and ulnar collateral ligaments.

Effect of combination of photobiomodulation 904 nm superpulsed laser therapy and Hippophae rhamnoides L. on third-degree burn wound healing.

Burn is a traumatic injury and aesthetic scarless repair poses a great challenge in area of cosmetic dermatology. Focus on multimode therapeutic strategies to promote healing of burns by regulating various stages of healing is warranted. Photobiomodulation therapy (PBMT), a non-invasive modality grabs the attention to repair impaired wounds. Seabuckthorn extract (SBTL-ALE) is known to possess antioxidant, anti-inflammation, and tissue-repair abilities. Current study aims to assess the effect of combination treatment of PBM 904 nm superpulsed laser and SBTL-ALE (2.5%) on repair of third-degree burn in rats. Rats were randomized into five groups: uninjured, control, SBTL-ALE, 904 nm PBMT, and combination. A transdermal burn wound was induced on the dorsal side of rats of all groups except the uninjured group and respective treatment was applied for 7 days postwounding. Dual treatment increased wound area contraction compared to control and either treatment alone. Immunohistochemical analyses exhibited increased angiogenesis, dermal hydration, collagen synthesis, and maintained redox homeostasis as evidenced by enhanced expression (p < 0.05) of CD31, aquaporin3, collagen type 3, Nrf2, and HO1 in combination group compared with control. Conversely, pro-inflammatory and oxidative stress markers exhibited reduced (p < 0.05) TNF-α, IL-6, IL-1β, NOS-2, ROS levels, and increased catalase activity in combined treatment. Furthermore, energy metabolizing enzymes viz. citrate synthase, CCO, and ATP contents were substantially (p < 0.05) increased, and LDH activity was reduced in the combination group. Dual treatment (PBMT + SBTL-ALE) prominently accelerates third-degree burn wound healing in rats, which could pave the path for multimode therapeutic strategies for the management of burns and dermal cosmetic care.

STRUCTURE OF BICARPELLATE GYNOECIUM IN &lt;i&gt;SYMPHYTUM&lt;/i&gt; &lt;i&gt;ASPERUM&lt;/i&gt; (BORAGINACEAE) IN RELATION TO EREM FORMATION

The genesis of the bicarpellate syncarpous gynoecium was analysed in Symphytum asperum in relation to the septa formation in it, which determines the structure of erems (a dispersal unit of schizogenetic fruits forming as a result of dividing each carpel of syncarpous gynoecium into two independent parts) and the coenobium as a whole. In the gynoecium, at early stages of development, a short fertile synascidiate zone arises due to the formation of a basal septum (septum of 1st type) at the fusing of the involute carpel edges. A symplicate zone is formed above. A double U-shaped synplacenta appears at the gynoecium base. The structure of the basal septum is characterized by some features. The sutures that form the septum are obsagittate, with their wide part directed towards the center, and their narrow part directed outward. The septum of the 1st type is characterized by a 4-rayed structure, resembling an elongated rhombus or 2 tetrahedral pyramids facing each other: short rays are located between the walls of emerging erems of the same carpel, and long rays are between the walls of the erems of adjacent carpels. The central part of the septum subsequently stops developing, and the rays are transformed into branches of syncarpous sutures (2 in each carpel), to form 4 septa of the 2nd type. The length of the septa of the 2nd type increases longitudinally. In the wall of the ovary on the dorsal side in the area of the vascular bundle, 4 strands of small thin-walled cells are formed. Then, a splitting of these strands and the dorsal vascular bundle in half takes place. The septa of the 2nd type, like curtains or inserts, connect open ventral margins with dorsal halves of the ovary wall in each carpel, later becoming part of the pericarp of single-celled erems. At the same time, the symplicate zone is divided into 4 independent compartments. In S. asperum, septa of the 2nd type do not divide the loculi of carpels into 2 compartments and are not united into single partitions. They remain autonomous, growing between open edges of the halves in each carpel. The resulting diaspores (erems) are surrounded by a fruit coat on all sides. The outgrowths are not detected between the erems. This growth of the septa of the 2nd type is unique and correlates with the growth of the gynobasic style, while the shape of the growing septa ideally coincides with the shape of its faces.

Two new species of the genus Samarangopus and the first record of Eurypauropusjaponicus (Arthropoda, Myriapoda, Pauropoda, Eurypauropodidae) from China.

Two new species, Samarangopustestudineussp. nov. from Hunan, South China and S.rotundifoliussp. nov. from Zhejiang, East China, are described and illustrated. Samarangopustestudineussp. nov. is characterized by unusual testudinal patterns on the dorsal side of the body and well-differentiated marginal protuberances on tergites. Samarangopusrotundifoliussp. nov. features large, round, leaf-shaped marginal protuberances and small, candle-like dorsal protuberances on tergites. Both of these species are compared to similar species in detail. In addition, Eurypauropusjaponicus Hagino & Scheller, 1985 is newly recorded from China.

Formation of the brain by stem cell divisions of large neuroblasts in Oikopleura dioica, a simple chordate.

Stem cell division contributes to the generation of various cell types during animal development, especially a diverse pool of neural cells in the nervous system. One example is reiterated unequal stem cell divisions, in which a large stem cell undergoes a series of oriented unequal divisions to produce a chain of small daughter cells that differentiate. We show that reiterated unequal stem cell divisions are involved in the formation of the brain in simple chordate appendicularians (larvaceans). Two large neuroblasts in the anterior and middle of the brain-forming region of hatched larvae were observed. They produced at least 30 neural cells out of 96 total brain cells before completion of brain formation at 10 hours after fertilization by reiterated unequal stem cell divisions. The daughter cells of the anterior neuroblast were postmitotic, and the number was at least 19. The neuroblast produced small daughter neural cells posteriorly every 20 min. The neural cells first moved toward the dorsal side, turned in the anterior direction, aligned in a single line according to their birth order, and showed collective movement to accumulate in the anterior part of the brain. The anterior neuroblast originated from the right-anterior blastomeres of the eight-cell embryos and the right a222 blastomere of the 64-cell embryo. The posterior neuroblast also showed reiterated unequal stem cell divisions, and generated at least 11 neural cells. Sequential unequal stem cell divisions without stem cell growth have been observed in protostomes, such as insects and annelids. The results provide the first examples of this kind of stem cell division during brain formation in non-vertebrate deuterostomes.

Characterization of the rat pituitary capsule: Evidence that the cerebrospinal fluid filled the pituitary cleft and the inner side of the capsule.

In humans, the pituitary gland is covered by a fibrous capsule and is considered a continuation of the meningeal sheath. However, in rodents some studies concluded that only the pars tuberalis (PT) and pars nervosa (PN) are enwrapped by the pia mater, while others showed that the whole gland is covered by this sheath. At PT the median eminence subarachnoid drains cerebrospinal fluid (CSF) to its cisternal system representing a pathway to the hypothalamus. In the present study we examined the rat pituitary capsule to elucidate its configuration, its physical interaction with the pituitary border and its relationship with the CSF. Furthermore, we also revisited the histology of the pituitary cleft and looked whether CSF drained in it. To answer such questions, we used scanning and transmission electron microscopy, intracerebroventricular infusion of Evan´s blue, fluorescent beads, and sodium fluorescein. The latter was measured in the pars distalis (PD) and various intracranial tissues. We found a pituitary capsule resembling leptomeninges, thick at the dorsal side of the pars intermedia (PI) and PD, thicker at the level of PI in contiguity with the PN and thinner at the rostro-ventral side as a thin membrane of fibroblast-like cells embedded in a fibrous layer. The capsule has abundant capillaries on all sides. Our results showed that the CSFs bathe between the capsule and the surface of the whole gland, and ciliate cells are present in the pituitary border. Our data suggest that the pituitary gland intercommunicates with the central nervous system (CNS) through the CSF.

Impact of Room-Temperature Storage on the Pecan Kernel Color, Carotenoids, Polyphenols, and Physicochemical Properties

This study aimed to investigate the changes in the pecan kernel color, carotenoids, polyphenols, and physicochemical properties during five months of storage at room temperature for five different pecan varieties. The results showed that the pecan kernel color darkened with a shift toward more red and less yellow during the storage. Additionally, the dorsal side of the kernel had a lighter color than the ventral side. Total carotenoids deceased from 92.0–118.8 to 45.2–101.9 μg/100 g of whole kernel, while total polyphenols had no significant differences (18.1–27.0 mg of GAE (gallic acid equivalent)/g of whole kernel) commonly. Three phenolics (gallic acid, catechin, and ellagic acid) were of 6.7–9.6, 31.4–46.7, and 11.7–16.2 mg/100 g of whole kernel and increased during storage. The pecan kernel moisture loss was significant, while the total lipids remained unchanged. Five texture parameters (hardness, toughness, slope, fracturability, and break) showed irregular changes. Genotypic variation was observed in all five varieties, although the storage was the main factor affecting the compositions.

Which side are you on? Spider web positioning affects prey capture more than body colour

Colour has been hypothesized to play a crucial role in prey capture for sit-and-wait predators that rely on visual cues to deceive their prey. Prey capture success has been directly linked to colouration in spiders; however, evidence so far focuses mostly on dorsal colouration, excluding ventral patterns that are visible to prey and may be relevant for prey attraction. Here, we explored whether the dorsal and ventral colouration of a colour polymorphic spider is associated with light environment and prey capture success. We quantified the number of prey captured across three dorsal (black, white, and yellow) and two ventral (black and a mosaic yellow/orange pattern) morphs of Gasteracantha cancriformis, considering light intensity on dorsal and ventral sides. We found that spiders capture more prey in low light environments, and that individuals often expose their dorsal colouration towards low light levels. We did not find significant differences in prey capture rate between morphs dorsally or ventrally. These results indicate that how and where spiders position their web can be more important for prey capture than colouration. Alternative hypotheses such as aposematism, camouflage and thermoregulation deserve more attention in future studies that aim to understand the role of colouration in spiders and the factors causing spider colour polymorphisms.

Redescription of an insect-associated nematode, Reiterina typica (Stefański, 1922) Sudhaus, 2011 (Rhabditida: Rhabditidae) found in scarab grubs in Hungary

Summary Three out of four currently accepted species of the genus Reiterina (Rhabditida: Rhabditidae) were described in the early 20th century. The type species of this genus, R. typica (Stefański, 1922) Sudhaus, 2011, has several synonyms, with differences in their individual species descriptions, which necessitates its detailed redescription. A population of this species was isolated from scarab beetles in Hungary and is characterised as follows: body 970 ± 123 μm long in males and 1221 ± 188 μm long in females, V% = 50.1-57.7, female tail conoid (94.5 μm, c = 13, c′ = 3.3), male tail conoid (36 μm, c = 27, c′ = 1.5) with anteriorly opened peloderan bursa supported by nine pairs of genital papillae (1 + 2 + 3 + 3), papillae 4 and 9 open on the dorsal side, and papillae 3 and 8 reaching the edge of the velum, spicules 28-47 μm long. Newly sequenced 18S rDNA genes place Reiterina typica in a clade with other published Reiterina typica sequence and with sequences from the genus Rhabditis.

Symmetry Breaking of Human Pluripotent Stem Cells (hPSCs) in Micropattern Generates a Polarized Spinal Cord-Like Organoid (pSCO) with Dorsoventral Organization.

Axis formation and related spatial patterning are initiated by symmetry breaking during development. A geometrically confined culture of human pluripotent stem cells (hPSCs) mimics symmetry breaking and cell patterning. Using this, polarized spinal cord organoids (pSCOs) with a self-organized dorsoventral (DV) organization are generated. The application of caudalization signals promoted regionalized cell differentiation along the radial axis and protrusion morphogenesis in confined hPSC colonies. These detached colonies grew into extended spinal cord-like organoids, which established self-ordered DV patterning along the long axis through the spontaneous expression of polarized DV patterning morphogens. The proportions of dorsal/ventral domains in the pSCOs can be controlled by the changes in the initial size of micropatterns, which altered the ratio of center-edge cells in 2D. In mature pSCOs, highly synchronized neural activity is separately detected in the dorsal and ventral side, indicating functional as well as structural patterning established in the organoids. This study provides a simple and precisely controllable method to generate spatially ordered organoids for the understanding of the biological principles of cell patterning and axis formation during neural development.

Confirmation of the existence of Himalayan long-eared bats, Plecotushomochrous (Chiroptera, Vespertilionidae), in China.

The existence of Himalayan long-eared bats, Plecotushomochrous (Chiroptera, Vespertilionidae), in China has not been previously confirmed. In this study, four bats captured with harp traps from two sites in the Maoershan National Nature Reserve in Guangxi, China were investigated. These bats have long, wide auricles, each with a prominent tragus. The length of each auricle is about the same as that of a forearm. Hairs on the ventral fur have a dark base with mixed grey and yellowish tips; those on the dorsal fur also have a dark base and are bicolored with brown tips. The thumbs are very short. A concavity is present in the front of the dorsal side of the cranium. Based on morphological characteristics and phylogeny using Cyt b gene sequences, these bats were identified as P.homochrous, thus confirming the existence of Himalayan long-eared bats in China.

Transperineal pelvic floor ultrasound in male.

The pelvic floor (PF) is a highly complex structure which may be affected by various stimulating factors like decreased PF support. As ultrasound can dynamically observe the position and mobility of anatomical structures, However, there are very few studies on PF ultrasound in males. Twenty-one male patients with normal conditions underwent transperineal pelvic floor ultrasound (TPFU) examination. Ultrasound was performed in a supine lithotomy position. The probe was pressed on the sagittal plane of the perineum and adjusted till the anorectal angle, as well as bladder, were located and the median prostate and pubic symphysis were visible on the sagittal plane. TPFU was carried out to observe the patterns of pelvic floor movement during different phases, measure ultrasound parameters of the PF in men, and assess the potential applications and prospects of the male PF. Two-dimensional male PF ultrasound can detect the bladder, prostate, male urethra, anus, rectum. Resting, Valsalva, and contraction phases of the PF are clearly shown, the pelvic organs in the Valsalva phase shift to the dorsal foot side, and shift to the cephalic ventral side when the levator ani muscle (LAM) contracts. Three-dimensional male PF ultrasound can visually show the shape and structure of the levator ani muscle hiatus. It is a feasible examination tool for detecting PF disorders. However, there are still many fields to explore in the future.

Lesser omental hernia through a defect in the posterior layer of the lesser omentum

BackgroundIn previously reported cases of lesser omental hernia, a rare clinical presentation, the herniated intestinal tract was passing through both peritoneal layers of the lesser omentum to herniate into the peritoneal cavity or bursa omentalis. Here we present a very rare case of lesser omentum hernia, where the transverse colon entered through only the posterior layer of the lesser omentum to form a hernia between the anterior and posterior layers.Case presentationA 43-year-old man was admitted to the emergency department with acute abdominal pain. Plain abdominal computed tomography (CT) revealed a change in the caliber of the transverse colon between the stomach and pancreas, forming a closed loop on the cephaloventral side of the stomach. On contrast-enhanced CT images, vessels were observed in the contrast-enhanced lesser omentum surrounding the herniated intestine. The patient was diagnosed with a lesser omental hernia and underwent laparoscopic surgery. Intraoperatively, the transverse colon was covered by the anterior layer of the lesser omentum, and a defect was found in the posterior layer of the lesser omentum on the dorsal side of the stomach. A 2-cm incision was made in the posterior layer of the lesser omentum to widen the small defect. The herniated intestinal section was removed from the hernia sac, and the transverse colon was retained unresected. The postoperative course was uneventful.ConclusionsAs illustrated in this first case of a lesser omental hernia forming between the anterior and posterior layers, characteristic CT findings may play an active role in the diagnosis of this rare presentation.

Repeatability of high-resolution laser Doppler images of the hands in patients with systemic sclerosis and secondary Raynaud's phenomenon.

The objective of the study was to establish the repeatability of baseline diagnostic images of the dorsum of the hands acquired using a high-resolution laser Doppler imager in patients with Raynaud's phenomenon secondary to systemic sclerosis (SSc). The dorsal side of the hands of 22 patients (8 male 14 female), age range 29-73, median 62, with SSc and secondary Raynaud's phenomenon were imaged over two consecutive days at approximately the same time using a Moor Instruments' high-resolution laser Doppler imaging unit. The images were analysed by taking regions of interest at discrete locations in the images to calculate dimensionless values of flux (PU). Repeatability of the diagnostic investigation was assessed using methods described by Bland and Altman and by also plotting the results from visit 1 against visit 2 and calculating the line of best fit. Based on the criteria that 95% of all measurement differences should be within a factor of 1.96 of the standard deviations of the mean values, then high-resolution laser Doppler imaging technique is probably repeatable when acquiring and analysing baseline images of patients with Raynaud's phenomenon secondary to SSc. However, a larger study with more patients is required to prove this conclusively-as only data from 19 patients were analysed (3 patients were not included due to technical issues)-and was therefore susceptible to marked clinical variations in patients presenting on different days for the investigations.

Wrist Extensor Tenosynovitides: A Case Report

Background: Rice bodies can be found in rheumatic diseases, infectious diseases, and osteoarthritic joints. Rice bodies' most common locations include the subacromial bursa of the shoulder and the knee, while rice body synovitis of the wrist extensor tendons is uncommon. We have presented the case of tuberculous tenosynovitis with rice body formation in the extensor tendon sheaths of the hand and wrist.&#x0D; Case Report: A 51-year-old man presented with swelling and mild pain in the dorsal side of left wrist, hand, and proximal phalanx of the second finger. He stated a history of traumatic injury to the proximal phalanx of the index finger. Radiographs showed a softtissue mass shadow, and magnetic resonance imaging (MRI) showed edema and soft tissue swelling around extensor tendons extending into the distal forearm and ulnar side of the second finger in favor of tenosynovitis. Laboratory test results were normal. The patient had a negative Mantoux test result and no history of mycobacterial exposure. Surgical exploration of the lesion revealed rice bodies in the synovial sheath of extensor tendons in the wrist, extending distally to the dorsal aspect of the hand, especially the radial side. Removal of the rice bodies and complete excision of the sheath and tenosynovectomy was performed.&#x0D; Conclusion: As in our case, even in the absence of past tuberculosis (TB) infection or exposure, Mycobacterium TB (MTB) should be considered in the differential diagnosis of long-standing extensor tenosynovitis in the hand and wrist.

β Oscillations of Dorsal STN as a Potential Biomarker in Parkinson's Disease Motor Subtypes: An Exploratory Study.

Parkinson's disease (PD) can be divided into postural instability and difficult gait (PIGD) and tremor dominance (TD) subtypes. However, potential neural markers located in the dorsal ventral side of the subthalamic nucleus (STN) for delineating the two subtypes of PIGD and TD have not been demonstrated. Therefore, this study aimed to investigate the spectral characteristics of PD on the dorsal ventral side. The differences in the β oscillation spectrum of the spike signal on the dorsal and ventral sides of the STN during deep brain stimulation (DBS) were investigated in 23 patients with PD, and coherence analysis was performed for both subtypes. Finally, each feature was associated with the Unified Parkinson's Disease Rating Scale (UPDRS). The β power spectral density (PSD) in the dorsal STN was found to be the best predictor of the PD subtype, with 82.6% accuracy. The PSD of dorsal STN β oscillations was greater in the PIGD group than in the TD group (22.17% vs. 18.22%; p < 0.001). Compared with the PIGD group, the TD group showed greater consistency in the β and γ bands. In conclusion, dorsal STN β oscillations could be used as a biomarker to classify PIGD and TD subtypes, guide STN-DBS treatment, and relate to some motor symptoms.
