The Effect of Palm Pollen Extract on Sexual Disorders in Postmenopausal Women: A Randomized Clinical Trial.

Considering the numerous nutritional and estrogenic compounds of palm pollen and their effect on sexual function, this study was performed to investigate the effect of palm pollen extract on sexual disorders in postmenopausal women. In this three-blind clinical trial, 110 postmenopausal women from December 2019 to December 2020 from Rafsanjan comprehensive health service centers were randomly assigned to two groups, using a lottery method. The intervention group received 300 mg capsule of palm pollen extract, and the control group received placebo for 4 weeks. Sexual disorders were assessed with a 6-item female sexual function index before, at the end of the intervention, and 4 weeks after the end of the intervention. Independent t-test, Chi-square and repeated measures ANOVA were used to analyze the data through SPSS software version 21. The statistically significant level was considered P value less than 0.05. The mean scores of sexual disorders before the intervention in the intervention and control groups were 15.36±5.01 and 14.13±4.67 (P=0.68); at the end of the intervention, they were 15.18±4.50 and 14.22±3.91 (P=0.43) and 4 weeks after the end of the intervention we obtained 15.7±4.77 and 14.44±3.78, respectively (P=0.90). According to the results, daily consumption of 300 mg of date pollen extract had no effect on improving sexual disorders in postmenopausal women. Further studies in this field are suggested.Trial Registration Number: IRCT20160308026971N1.

Comparison between Iraqi Jenoubi heifers and bulls fed on date palm pollen to accelerate puberty and sexual maturit

The objective of the current study was to compare puberty and sexual maturity in Iraqi Jenoubi bulls and heifers that were fed date palm pollen (DPP) in their diets. Ten Jenoubi heifers and ten bulls, 6-month-old were divided randomly into two treatments: DPP treatment (T1) supplemented with 2 g of DPP/ head/day and control treatment (T2) was not supplemented with DPP. In heifers, the overall mean value of control group was significantly lower (27.53, 0.96 ng/ml and 9.44 pg/ml) than treatment group (70.42, 18.27 ng/ml and 19.16 pg/ml) for FSH, LH and estrogen, respectively in puberty period. Similar trend was noticed for hormone concentrations (FSH, LH, Estrogen and Testosterone) for bulls at puberty and maturity age. In bulls, T1 was significantly higher (155 and 212.5 kg) than control group (139.5 and 196 kg) for body weight in puberty and maturity age respectively, and in heifers T1 was significantly higher (150.33 and 206.66 kg) than control group (142 and 198.66 kg) for body weight in puberty and maturity age respectively, and same trend was observed for body condition score (BCS). It can be concluded that adding date palm pollen to ration of heifers and bulls accelerates puberty and maturity in heifers and bulls. But the acceleration in heifers was more than in bulls.

A Biosecurity Tool: High-Intensity, Pulsed Polychromatic Light and UV-C Treatments of Oil Palm Pollen and Spores of Fusarium oxysporum f. sp. elaeidis

The movement of oil palm ( Elaeis guineensis) pollen as a germplasm material between oil palm-growing countries for the purposes of plant-breeding programs is common in West Africa, Southeast Asia, and South America. Reports of pollen contamination with Fusarium oxysporum f. sp. elaeidis ( Foe), the causal agent of Fusarium wilt disease for oil palm, heightened the need for an operational decontamination technique for oil palm pollen prior to export. In this study, high-intensity, pulsed polychromatic light (HIPPL) and conventional UV (UV-C) were used as decontamination tools to treat Foe spores and oil palm pollen. We combined qualitative studies for HIPPL- and UV-C-treated Foe spores and quantitative studies for treated pollen. The study showed that despite UV-C and HIPPL successfully controlling Foe, oil palm pollen had reduced viability or was inviable upon exposure to various doses of UV-C and HIPPL sources. The effects of UV-C at doses of 2.5, 5, and 10 kJ/m2 and HIPPL at 10, 20, and 40 pulses were determined for oil palm pollen and Foe germination. UV-C doses of 10 kJ/m2 and 40 pulses of HIPPL showed significant reduction in germination of oil palm pollen but had no adverse effect on Foe viability. At 60 kJ/m2 of UV-C and 240 pulses of HIPPL, Foe was inviable, and pollen could not germinate. [Formula: see text] Copyright © 2022 The Author(s).

Honey quality from the bee Apis cerana, honey potency produced by coconut and sugar palm saps

Abstract. Erwan, Agussalim. 2022. Honey quality from the bee Apis cerana, honey potency produced by coconut and sugar palm saps. Biodiversitas 23: 5854-5861. One of the big problems when keeping honeybees is the limited sustainable feed, especially in the rainy season. The objectives of this study were to evaluate the honey quality from the bee Apis cerana based on the chemical composition and honey potency produced by the coconut and sugar palm saps. This study using thirty colonies of the bee A. cerana was divided into six treatments consisting of sugar palm sap without sugar palm pollen, coconut sap without sugar palm pollen, coconut sap of 50% + sugar palm sap of 50% without sugar palm pollen, sugar palm sap was added by sugar palm pollen; coconut sap was added by sugar palm pollen; coconut sap of 50% + sugar palm sap of 50% was added by sugar palm pollen. The chemical composition of honey from the A. cerana was moisture (20.76 to 21.80%), reducing sugar (62.78 to 68.37%), sucrose (1.44 to 3.42%), diastase enzyme activity (5.17 to 9.04 DN), hydroxymethylfurfural (2.24 to 5.81 mg/kg), and acidity (26.00 to 36.33 mL NaOH/kg). Honey potency produced by the coconut and sugar palm saps in 100 hectares area produces honey was 1542.857 tons/year and 1150 tons/year, respectively. It can be concluded that the quality of A. cerana honey, produced by the sugar palm and coconut saps, is acceptable by the Indonesian national and international standards. The sugar palm and coconut saps have big potential as bee feed, especially for the bee A. cerana.

Effect of Extender Supplemented with Date Palm Pollen Grain on Caprine Semen Qualities

Date Palm Pollen Grain (DPPG) were proved to maintain semen characteristics and quality in bulls, equines, and buffaloes. However, DPPG as supplementation in the extender for goats are scarce. Hence, the aims of this research were to investigate the semen motility and viability and to examine the functional membrane integrity of semen in different concentrations of DPPG supplemented in goat semen extenders. In this study, DPPG was added with 4% and 8% in tris-citrate-fructose-yolk (TCFY) semen extender and chilled at 5°C for 0, 24 and 48 hours. The diluted semen samples were assessed for sperm motility, viability, and membrane integrity. A total of four ejaculations from two Boer bucks were used in this study. The results indicated that the ability to maintain sperm viability was significantly higher in the extender supplemented with 8% DPPG in all storage times (P<0.05). Furthermore, 8% of DPPG in extender significantly improved sperm motility after 48 hours (56.67±5.57) compared to control (0% DPPG) (40.83±3.00) and 4% DPPG (43.33±5.24). Results also showed that sperm membrane integrity percentage in 8% DPPG (40.00±4.04) was significantly higher than control (30.33±2.19) at 0-hour storage time. The extender supplemented with 8% DPPG indicated the best result in maintaining sperm quality after 24 hours of chilled storage compared with other treatments. In conclusion, 8% of DPPG supplemented in semen extenders proved to maintain viability, motility and membrane integrity compared to control.

Optimized Primary Culture and Subculture of Granulosa Cells

Background: Primordial follicle includes an oocyte surrounded by a layer of somatic cells called Granulosa Cells (GCs). GCs, also known as nurse cells, are an important protective element for the growth and survival of oocytes. Oocytes, which lack some of the metabolic processes, require granulosa cells for their development.&#x0D; Objectives: This manuscript was provided to explain the protocol of GCs primary culture extracted from NMRI mice ovaries.&#x0D; Methods: For choosing the optimum protocol, we used two methods with different culture mediums to obtain more GCs and expedite the process. Hematoxylin and Eosin (H&amp;E) staining and flow cytometry were used to analyze the type of extracted cells from ovaries. Besides, we evaluated the effect of crocin and DPP as two common natural products in Iran on the proliferation of these cells via MTT assay.&#x0D; Results: Second protocol method and alpha-MEM culture medium were chosen based on the results. Our findings from HE staining and flow cytometry proved the percentage of cultured GCs in the flask. Further, MTT assessment demonstrated that crocin at high doses had a toxic effect on granulosa cells, whereas date palm pollen (DPP) stimulated them to proliferation.&#x0D; Conclusion: Modifying this protocol is for the improvement of proliferation, coherence, and quality of GCs in primary culture and subculture. Regarding the effect of these two natural products on granulosa cells, we can mention the bilateral effect of crocin and DPP enhancement in proliferation.

Effects of different pollen diets in comparison to a natural prey, Tetranychus turkestani (Acari: Tetranychidae), on development, survival, and reproduction of Euseius scutalis (Acari: Phytoseiidae)

The development, survival, and reproduction of the predatory mite Euseius scutalis (Athias-Henriot) (Acari: Phytoseiidae) were studied under laboratory conditions (25 ±1 °C, 65 ± 5% RH, 16:8 (L: D) h) on strawberry spider mite, Tetranychus turkestani Ugarov and Nikolski (Acari: Tetranychidae), and four different pollen including date palm, cattail, golden shower tree and caper bush pollen. Our results showed that E. scutalis mites successfully developed into the adult stage and reproduced on natural prey and plant pollen tested. Diet type significantly affected the developmental time of immature stages of both females and males. Females reared on T. turkestani had a considerably shorter total developmental time than those raised on other diets. Date pollen and spider mites-fed females began laying eggs much earlier than other females. The lower number of laid eggs was recorded for the females raised on golden shower tree, followed by caper bush pollen. The net reproductive rate (R0) of the predators fed golden shower tree was significantly lower than those provided cattail pollen and T. turkestani. Intrinsic and finite rates of increase (r and λ, respectively) were highest in the females fed T. turkestani (0.3300 ± 0.018 and 1.3910 ± 0.0247, respectively) followed by cattail pollen (0.2721 ± 0.0178 and 1.3126 ± 0.0233, respectively). Based on the current findings, it can be concluded that rearing of E. scutalis on the immatures of T. turkestani was considerably better than on other diets with higher values of egg production and population growth rate under laboratory conditions. Furthermore, cattail pollen followed by date palm pollen are suitable alternative diet sources for easy and cost-effective rearing of E. scutalis in the laboratory.

Effect of date palm pollen supplementation on female sexual function in non-menopausal women: A double blind randomized clinical trial

ObjectiveDespite numerous experimental studies in the literature, there are few clinical trials regarding the effect of date palm pollen (DPP) supplementation on sexual function improvement. In the present study, we sought to evaluate the impact of DPP on female sexual function in Iranian non-menopausal women. MethodsBetween October 2019 and December 2019, health centers in the city of Khalkhal, volunteers meeting the inclusion criteria were recruited in randomized clinical trials. Sixty-eight women were randomly stratified and assigned to one of the two study groups: placebo group (n = 35) and palm pollen group (n = 35), and received a starch or palm pollen capsule (300 mg per day), respectively, for 35 d. The Female Sexual Function Index (FSFI) instrument was used to assess female sexual function. ResultsAfter DPP supplementation, the increase in desire, lubrication, and the overall score, was statistically significant compared to the placebo group (P = 0.002, P = 0.000, and P = 0.042; respectively); Whilst there was no significant differences in the remaining domains (arousal: P = 0.763; orgasm: P = 0.370; satisfaction: P = 0.474; pain: P = 0.259). There was a statistically significant positive correlation between the coitus and preintervention levels of desire (r = 0.298, P = 0.038), arousal (r = 0.328, P = 0.021), lubrication (r = 0.361, P = 0.011), orgasm (r = 0.320, P = 0.025), satisfaction (r = 0.327, P = 0.022), and overall scores (r = 0.338, P = 0.018). ConclusionThis study suggests that DPP (300 mg supplementation for 35 d), given to non-menopausal women, could improve the lubrication and desire domains of FSFI.

Evaluation of Pollen Production of Common Male Date Palms Grown in the Mexicali Valley, Mexico

The aim of this study was the evaluation of date palm (Phoenix dactylifera L.) pollen production during the 2021 and 2022 seasons in the Mexicali Valley, Mexico. Twelve seed-propagated male palms of 20 years of age and similar vigor were selected and grouped into four groups with phenotypic characteristics of the common female cultivars in the area (Medjool, Deglet Noor, Khadrawy, and Zahidi). The pollen was extracted manually, with average production among all individuals of 780.94 and 777.11 g, in 26 and 24 inflorescences, respectively, for each year. Likewise, the flowering period on average was 47 and 41 days for each year. The pollen extracted from the earliest four inflorescences averaged 38.7 and 32.55 g, while that of the latest one produced 10.70 g and 18.28 g for each year, respectively. Seedling male palms with a phenotype similar to the Deglet Noor cultivar produced the greatest amount of pollen with 1250.98 and 1114.26 g on average for each year, produced during a late, short flowering period. Likewise, those palms with phenotypes similar to the Medjool cultivar produced the second-highest amount of pollen with 851.28 and 866.43 g on average for each year, produced during an early, long flowering period. Finally, an in vivo viability test through the fruit set percentage, revealed that the use of any of these four pollen sources would be suitable for the pollination of the recipient female cultivar Medjool, the most widely cultivated variety in Mexico. These results will allow date producers to select and propagate better pollen-producing male palms.

Pollen Alone or a Mixture of Pollen Types? Assessing Their Suitability for Mass Rearing of Neoseiulus cucumeris (Acari: Phytoseiidae) Over 20 Generations.

The generalist predatory mite, Neoseiulus cucumeris (Oudemans) is known as one of the most effective natural enemies on many pests. This economically important biocontrol agent was reared for 20 generations on date palm and castor bean pollen as well as a mixture of pollen types, including date palm, castor bean, and almond. The performance of this predator was evaluated by comparing its life table parameters after different generations (G1–G20) fed on each diet in a laboratory at 25 ± 1°C, 60 ± 5% RH, and a photoperiod of 16:8 (L: D) h. The development time of the predator reared on all tested diets had no significant difference in G20. The intrinsic rate of increase (r) of N. cucumeris by feeding on the mixed pollen (0.197 day−1) was significantly higher than that on castor bean, or date palm pollen (0.146 or 0.152 day−1 in G1, respectively). Our results indicated that the predator’s performance was not affected by long-term feeding on the pollen diets, as well as there was no considerable difference between pollen alone and pollen mixture diets. Furthermore, mites reared on pollen diets had higher quality than those reared on natural prey, Tetranychus urticae Koch.

Penambahan Polen Aren Sebagai Pakan Lebah untuk Meningkatkan Bobot Koloni Lebah Madu Trigona sp.

The aim of this study was to determine the effect of feed supplement in the form of sugar palm pollen on the increase in colony weight of Trigona sp. The study was conducted in Lembah Sari Village, Batulayar District, West Lombok Regency, which lasted for 4 weeks from May 2020-June 2020. Ten honey bee colonies of Trigona sp. were randomly assigned to two treatment groups with five replications each according to a completely randomized design. The treatment without palm pollen was placed differently with a distance of ±600 meters from the treatment using palm pollen and the distance between replicates was ±1 meter. The stages of the research include making the hive, selecting a colony from glodok, moving the colony to the hive, placing the research hive, and placing the palm pollen. The variables observed included the number of pollen cells and colony weights. The results showed that mean values for the number of pollen cells treated without and with palm pollen treatment from weeks 1-4 were 6,2±0,45, 7,0±0,71, 9,0±0,71, 12,2±0,84 and 6,4±0,55, 8,4±1,14, 11,8±0,84, and 15,4±1,14 respectively. While the colony weight for those with or without supplement were 0,15±0,04, 0,29±0,05, 0,44±0,05, 0,64±0,06 and 0,14±0,01, 0,39±0,09, 0,53±0,03, and 0,80±0,08. The average number of pollen formed and the colony weight for those given supplement was significantly higher than those without feed supplement. Thise results indicate the important of providing feed supplement in order to sustain productivity of Trigona sp. &#x0D; &#x0D;

Effect of Palm Pollen and Pomegranate Peel Supplementation on Sperm Development in Male Rabbits.

The use of plants, plant extracts, and folk remedies for the treatment of human diseases has been known as traditional medicine. It is approved that the use of herbal medicine dates far back to 60,000 years ago in Iraq. This study aimed to investigate the possible effects of pomegranate and palm pollen, as two powerful herbal remedies with antioxidant, anti-inflammatory, and anti-bacterial effects, on fertility in the male rabbits. A total of 15 healthy New Zealand White male adult rabbits were randomly assigned to three groups (n=5 in each group). Group A: 5 rabbits did not receive herbal treatment (control group). Group B: 5 rabbits were treated with palm pollen at a dose of 2 g by oral gavage daily. Group C: 5 rabbits were treated with pomegranate peel (2 g) treated by oral gavage daily. All animals were euthanized 90 days after the beginning of the experiment. Following the euthanasia, the testis was removed. For sperm recovery, the epididymis was dissected from the testicles and the tail of the epididymis was minced in the sperm washing medium and incubated for 15 min in an atmosphere of humidified 5% CO2, 95% The samples were evaluated by using computerized semen analyzer apparatus (CASA). After 90 days, the treated groups with palm pollen and pomegranate peel (groups B and C) demonstrated a significant increase in the sperm concentration, compared to group (A). Moreover, the recorded data revealed that the sperm concentration in group C was significantly higher than that in group B. The study indicated that the total sperm motility was increased significantly in groups B and C, as compared to that in the control group, while the total sperm motility in group C increased significantly, compared to group B. The histological evolutions signified that in the control group, the epithelial of seminiferous tubules were at different stages of spermatogenesis, the spermatocytogenesis (primary and secondary) with the spermogenesis (spermatids) were found in a cluster at the cavity of the tubule. Furthermore, the results of histological evaluations in groups B and C were distinguished by a significant augmentation of the seminiferous tubules with primary and secondary spermatocytes, as well as some degrees of spermogenesis (round spermatids), compared to group A. Moreover, increased angiogenesis was observed in groups B and C. In conclusion, the results pointed out that herbal remedies have a significant effects in the treatment of reproductive disorders.

Ginseng, Tribulus Extracts and Pollen Grains Supplementation Improves Sexual State, Testes Redox Status, and Testicular Histology in Nile Tilapia Males.

This study aimed to investigate the effect of dietary supplementation of three natural antioxidants on sex hormone levels, enzymatic and non-enzymatic antioxidant systems, and histological changes in the testes of male Nile tilapia, Oreochromis niloticus. A total of 210 male Nile tilapia were distributed into seven treatments (three replicates for each) with an initial weight of 3.67 g fish−1. The fish were fed experimental diets (32% crude protein) without supplementation as control or supplemented with ginseng extract (GE; 0.2 and 0.4 g GE kg−1 diet), Tribulus terrestris extract (TT; 0.6 and 1.2 g TT kg−1 diet), and date palm pollen grains (DPPG; 3 and 6 g DPPG kg−1 diet) for 84 days. The results revealed a significant increase in the luteinizing hormone level with TT, DPPG, and GE supplementation increased the levels by 22.9%, 18.5%, and 17.6%, respectively. The testosterone level also increased significantly with TT1.2, GE0.4, TT0.6, and DPPG6 by 86.23%, 64.49%, 57.40%, and 24.62%, respectively. The antioxidant status in the testis homogenate showed a significant decrease in the level of thiobarbituric acid-reactive substances when using different dietary substances. In addition, glutathione reduced contents, glutathione S-transferases, glutathione peroxidase, catalase, and superoxide dismutase activities significantly increased with different dietary supplementation in a dose-dependent manner. The histological evaluation revealed normal histological features of the testes in all treatments with increasing active seminiferous tubules (%) in GE, TT, and DPPG supplemented groups, especially with the highest levels. In conclusion, the dietary supplementation of GE, TT, and DPPG enhanced sex hormones level, redox status, and testis structure and could improve the male reproductive performance of Nile tilapia.

Efficacy of Date Palm Pollen in the Male Sexual Dysfunction after Coronary Artery Bypass Graft: A Randomized, Double-Blind, Clinical Trial.

Background Bypass graft surgery of the coronary artery has a significant effect on the creation and development of sexual dysfunction among male patients. The previous studies have demonstrated that date palm pollen (DPP) increases the count and quality of sperm. Additionally, it has been shown that DPP has a protective effect against myocardial infarction and cardiac remodeling. Therefore, this is the first study investigating the impact of DPP (Phoenix dactylifera L.) on managing male sexual dysfunction after coronary artery bypass graft. Methods This randomized, double-blind, placebo-controlled clinical trial was conducted on 60 patients (DPP group n = 30, control group n = 30) of Iranian men after coronary artery bypass graft. Two parallel groups were randomly generated from the study participants. The intervention group was prescribed 3 grams of the powder of DPP twice a day (9 AM and 9 PM) for two months, while the control group received the same prescription of the placebo powder. Results The DPP consumption significantly increased the International Index of Erectile Function (IIEF) (from 23.21 to 46.57) and the Hurlbert Index of Sexual Desire (HISD) (from 59.39 to 64.45) scores over time in the intervention group. However, there were no significant changes in the control group. Conclusion Daily intake of 6 g DPP for two months exhibited beneficial effects on the symptoms of male sexual dysfunction in patients who have undergone coronary artery bypass graft (CABG).
